    SUMMARY *
    Habeas Corpus
    The panel affirmed the district court’s judgment granting
    Robert Leeds’s 
    28 U.S.C. § 2254
     habeas corpus petition
    challenging his Nevada first-degree murder conviction for
    killing William Scarborough.
    Although Leeds resided at the house where the murder
    occurred, the prosecution presented a felony-murder theory
    at trial, alleging that Leeds committed the murder during the
    course of a burglary because he entered the home’s garage
    as he struggled with Scarborough. Leeds’s trial counsel
    failed to argue that a person cannot burglarize his own home.
    The jury’s general verdict form did not specify whether the
    jury relied on the felony-murder theory or the State’s
    alternative theory of willful, deliberate, and premeditated
    murder to convict Leeds of first-degree murder.
    Leeds sought state habeas relief, but his post-conviction
    counsel failed to allege in the petition that trial counsel was
    ineffective for failing to argue that Leeds could not
    burglarize his own home. The claim was therefore
    procedurally defaulted under Nevada law.
    Applying Martinez v. Ryan, 
    566 U.S. 1
     (2012), the
    district court excused Leeds’s procedural default on the basis
    of post-conviction counsel’s ineffective assistance and the
    resulting prejudice to Leeds. The district court then granted
    relief on the merits of the underlying trial-level ineffective

    assistance of counsel (IAC) claim, finding that Leeds’s trial
    counsel performed ineffectively under Strickland v.
    Washington, 
    466 U.S. 668
     (1984), by failing to raise the
    burglary argument and prevent the use of the felony-murder
    theory.
    The panel agreed with the district court.
    The panel held that Leeds established a basis to excuse
    the procedural default of his claim because (1) Leeds’s trial-
    counsel IAC claim is substantial and therefore satisfies
    Martinez’s prejudice requirement; and (2) Leeds’s post-
    conviction counsel provided ineffective assistance under
    Strickland, meeting the Martinez cause requirement.
    The panel held that Leeds is entitled to relief on the
    merits because (1) trial counsel’s failure to raise the
    objectively important burglary argument constituted
    deficient performance; and (2) there is a reasonable
    probability that the result of the proceeding would have been
    different without the use of the felony-murder rule, such that
    the deficient performance prejudiced Leeds.

    OPINION
    PAEZ, Circuit Judge:
    The State of Nevada appeals the grant of Petitioner
    Robert Leeds’s 
    28 U.S.C. § 2254
     petition for a writ of habeas
    corpus. In 2006, a Nevada jury convicted Leeds of first-
    degree murder for killing William Scarborough. Although
    Leeds resided at the house where the murder occurred, the
    prosecution presented a felony-murder theory at trial,
    alleging that Leeds committed the murder during the course
    of a burglary because he entered the home’s garage as he
    struggled with Scarborough. Leeds’s trial counsel failed to
    argue that a person cannot burglarize his own home. The
    jury’s general verdict form did not specify whether the jury
    relied on the felony-murder theory or the State’s alternative
    theory of willful, deliberate, and premeditated murder to
    convict Leeds of first-degree murder.
    Leeds later sought state habeas relief, but his post-
    conviction counsel failed to allege in the petition that trial
    LEEDS V. RUSSELL                      5
    counsel was ineffective for failing to argue that Leeds could
    not burglarize his own home. The claim was therefore
    procedurally defaulted under Nevada law. Leeds then filed
    a habeas petition in federal district court, which the court
    ultimately granted. The court, applying Martinez v. Ryan,
    
    566 U.S. 1
     (2012), first excused Leeds’s procedural default
    on the basis of post-conviction counsel’s ineffective
    assistance and the resulting prejudice to Leeds. The court
    then granted relief on the merits of the underlying trial-level
    ineffective assistance of counsel claim, finding that Leeds’s
    trial counsel performed ineffectively under Strickland v.
    Washington, 
    466 U.S. 668
     (1984), by failing to raise the
    burglary argument and prevent the use of the felony-murder
    theory.
    We agree with the district court and affirm. Leeds has
    established a basis to excuse the procedural default of his
    claim, and he is further entitled to relief because his trial
    counsel provided constitutionally ineffective assistance.
    I.
    1.
    Petitioner Robert Leeds and Sally Lane married in 1985.
    Throughout their marriage, Leeds experienced mental
    illness, including severe depression and bipolar disorder. In
    2000, Lane moved to Canada to attend veterinary school.
    Leeds moved in with Lane’s mother, but he became deeply
    depressed and fell into a “comatose” state. After he had a
    falling out with his mother-in-law, he joined his wife in
    Canada. Four years later, Lane needed money for veterinary
    school, but her family no longer approved of Leeds. Her
    brother conditioned his financial assistance on her agreeing
    to divorce Leeds. Lane filed for divorce in 2004. The
    divorce became final in April 2005. Leeds and Lane,
    6                      LEEDS V. RUSSELL
    however, continued to live together, share a dog and a car,
    and have a “cooperative” relationship.
    Lane graduated from veterinary school in June 2005. At
    that time, Lane had some concerns about her and Leeds’s
    relationship, but she continued to feel connected to Leeds.
    The pair decided to move to Las Vegas together, where they
    leased a home on Evening Song Avenue (“Evening Song
    house”). Although only Lane’s name was on the lease, there
    was “no doubt” that Leeds would be living there too. Leeds
    never had a key to the house, but he did not need one because
    they always left the back door open.
    In September 2005, Lane started working at an animal
    shelter and met William Scarborough, who euthanized
    animals that had to be put down. Scarborough had been in
    prison and had recovered from an alcohol and drug
    addiction. Lane told Leeds about Scarborough, and Leeds
    cautioned her to keep her distance given Scarborough’s job
    and background. Leeds also worried Lane would begin an
    emotional affair with Scarborough, as she was “vulnerable”
    at work because she loved animals and did not like seeing
    them euthanized. In mid-October, Scarborough and Lane
    started rescuing some of the animals that were to be
    euthanized. They became close and started a romantic
    relationship towards the end of October. Also in October,
    Lane told Leeds “a couple times” that “it would be better if
    [they] were separated for a while,” but she did not leave him,
    and he did not move out.
    In November, Lane’s family planned to visit for
    Thanksgiving. Because her family was unaware that Leeds
    was still in her life, Lane told Leeds that they needed to move
    his belongings out of the Evening Song house and that he
    could not stay there while her family visited. The “only
    LEEDS V. RUSSELL                      7
    purpose” Lane had in asking Leeds to leave for the holiday
    was that her family not find out she still lived with him.
    Leeds had started working as an English teacher, so Lane
    took him to his office “to stay there temporarily,” beginning
    on Wednesday of Thanksgiving week. Shortly before the
    holiday, Leeds ran out of his psychiatric medications.
    Lane spent Thanksgiving with her brother and
    Scarborough, though her mother ultimately did not visit.
    The day after Thanksgiving, Scarborough helped Lane buy
    furniture and move it into the Evening Song house. While
    they were out to dinner that night, Leeds called Lane’s
    mother and learned that she was not visiting Lane. Leeds
    went to the Evening Song house around 11 p.m. and let
    himself in through the back door as usual. Leeds went
    upstairs, saw the new futon bed, and “lost it” because he “felt
    [like he] was walking in on a love nest in [his] own house.”
    Around 2 a.m., Lane and Scarborough returned to the house.
    Lane described Leeds as “devastated” and “hysterical.”
    Leeds also said he was sobbing and felt like he was in a
    nightmare. Leeds called 911, saying “something to the
    effect that there is a convicted felon . . . [who] works at my
    wife’s office[] and he has been . . . conning her all along.”
    Lane also called 911 at Scarborough’s direction, saying that
    her ex-husband was in the house.
    The police arrived and separated Lane, Scarborough, and
    Leeds. Lane told police that Leeds was “no longer staying
    there,” “was physically out of the house, but he was . . . not
    told he couldn’t come back,” and that Lane was hoping
    Leeds would find his own place. The police explained that
    Leeds “had the right to stay because he’d been living there”
    and that Lane would need to get an eviction notice. Leeds
    told the police he felt like dying because he was losing his
    wife, and the police offered to take him back to his office to
    8                      LEEDS V. RUSSELL
    “sleep this off.” Leeds went to his office, and Scarborough
    stayed at the Evening Song house with Lane. Leeds called
    the house twice, but Scarborough answered and said Lane
    did not want to talk to him.
    The next morning, Leeds came to the house and spoke to
    Lane from the front porch. Leeds told Lane he was sorry for
    his behavior the night before. He was apologetic. He was
    holding cash, saying it was for rent. Leeds said he was going
    to Florida to be with his family and that they could reconcile.
    Lane was crying and “weakening,” and Scarborough told her
    to “stay strong” in her decision to separate.
    Ultimately, Scarborough offered Leeds a ride to the
    airport, which he accepted. The men got in Scarborough’s
    truck, which was in the driveway. Leeds then asked to hug
    his dog, to hug Lane, to give Lane the money, to use a cell
    phone, and to have a drink of water. At some point,
    Scarborough became frustrated and got out of the truck.
    Scarborough and Lane went up toward the garage to talk,
    and Leeds remained near the truck on the phone with his
    family.
    Suddenly, Lane saw Leeds drop the phone and rush
    toward Scarborough. The two men fell to the ground,
    struggling, and rolled into the garage. Lane thought Leeds
    was punching Scarborough, and she started hitting Leeds in
    the back, trying to make him stop. Lane’s hand was injured.
    She then saw blood on Scarborough’s face and saw Leeds
    holding a knife, which Leeds testified he grabbed from
    Scarborough. Leeds stabbed Scarborough in the chest and
    said something to the effect of: “Die like the animals you
    kill.” Scarborough fell to the ground. Leeds then went to
    the truck, picked up a tire iron, came back, and hit
    LEEDS V. RUSSELL                                9
    Scarborough in the head around eight times. 1 Leeds then left
    through the gate of the housing community and attempted
    suicide by cutting his wrists.
    2.
    The State of Nevada charged Leeds with murder with use
    of a deadly weapon; attempted murder with use of a deadly
    weapon; battery with use of a deadly weapon resulting in
    substantial bodily harm; and burglary while in possession of
    a deadly weapon. The burglary charge was included because
    the prosecutor argued that Leeds intended “to assault, batter,
    or murder” Scarborough when the two men entered the
    garage during their struggle. At trial, the jury was instructed
    that they could convict Leeds of first-degree murder based
    on either a felony-murder theory (because of the burglary)
    or a willful, deliberate, and premeditated theory. In closing
    argument, the prosecutor explained that it did not matter if
    the jurors agreed on one theory: they could convict Leeds of
    first-degree murder as long as they all thought one of the two
    theories applied.
    The jury convicted Leeds on all four counts, although the
    court later dismissed the battery count. The verdict form
    does not specify which theory of murder the jury relied upon
    to convict Leeds of first-degree murder. For the first-degree
    murder count, Leeds was sentenced to twenty years to life,
    with a consecutive twenty years to life for the use of a deadly
    weapon. For the attempted murder count, he was sentenced
    to six to twenty years, with a consecutive term of six to
    twenty years for the use of a deadly weapon. Finally, for the
    burglary count, Leeds was sentenced to a concurrent term of
    1
    At trial, a medical examiner testified that the cause of death was the
    stab wounds to the chest, not the impact of the tire iron.
    10                     LEEDS V. RUSSELL
    four to thirteen years. Leeds appealed his convictions, but
    the Nevada Supreme Court ultimately affirmed. See Leeds
    v. State, 
    281 P.3d 1194
     (Nev. 2009) (unpublished table
    opinion).
    3.
    Leeds then initiated state habeas proceedings. In
    Nevada, a post-conviction collateral proceeding is the first
    opportunity to raise ineffective assistance of counsel claims.
    See Gibbons v. State, 
    634 P.2d 1214
    , 1216 (Nev. 1981)
    (concluding that the “appropriate vehicle for presenting a
    claim of ineffective assistance of counsel is through post-
    conviction relief”). Leeds first filed a pro se habeas petition,
    which was denied. The Nevada Supreme Court reversed and
    remanded with instructions to appoint counsel. In July 2013,
    Leeds’s state-appointed post-conviction counsel (“PCC”)
    filed a supplemental petition alleging multiple errors by trial
    counsel, but the petition did not include a claim that trial
    counsel was ineffective for failing to challenge the felony-
    murder theory on the ground that Leeds could not burglarize
    his own home (the “burglary theory”). The state district
    court denied his petition.
    Leeds filed a timely appeal to the Nevada Supreme Court
    in September 2014. For the first time, PCC asserted the
    burglary theory, arguing that the felony-murder rule was
    improperly applied, and citing United States Supreme Court
    precedent mandating reversal in such situations. See Yates
    v. United States, 
    354 U.S. 298
    , 312 (1957) (a verdict should
    be set aside “in cases where the verdict is supportable on one
    ground, but not on another, and it is impossible to tell which
    ground the jury selected”), overruled on other grounds by
    Burks v. United States, 
    437 U.S. 1
     (1978). For support, PCC
    cited the then-recently decided Nevada Supreme Court case
    LEEDS V. RUSSELL                     11
    State v. White, 
    330 P.3d 482
     (Nev. July 10, 2014), which
    made clear that a person cannot burglarize his own home, 
    id. at 483
    . The Nevada Supreme Court, however, affirmed the
    denial of the habeas petition and explicitly declined to
    consider the burglary theory because this “ground for relief
    was not raised in Leeds’ post-conviction petition for a writ
    of habeas corpus or argued in the district court below.”
    Because Leeds failed to raise the burglary theory before the
    state district court, the claim was procedurally defaulted and
    was never reviewed by a state court. See 
    Nev. Rev. Stat. § 34.810
    (1)(b).
    4.
    Leeds next filed a petition for habeas relief in federal
    district court under 
    28 U.S.C. § 2254
    . The State filed a
    motion to dismiss, which was granted in part and denied in
    part. The parties then briefed the remaining claims.
    Relevant here is Ground Two, which alleged that “[t]rial
    counsel was ineffective for failing to challenge the burglary
    charge and felony murder theory on the ground that Mr.
    Leeds could not burglarize his own home.”
    The district court granted habeas relief as to Ground Two
    in September 2021. It did not address the remaining
    grounds. The court found that Leeds’s procedural default of
    Ground Two was excused under Martinez. The court then
    addressed the merits of the claim, finding that trial counsel
    had performed ineffectively under Strickland. The State
    timely appealed.
    II.
    We have jurisdiction under 
    28 U.S.C. § 2253
    . Leeds’s
    habeas petition is governed by the Anti-Terrorism and
    Effective Death Penalty Act, 
    28 U.S.C. § 2254
     (“AEDPA”).
    12                    LEEDS V. RUSSELL
    We review de novo the district court’s decision on the habeas
    petition, including questions of procedural default. Sexton
    v. Cozner, 
    679 F.3d 1150
    , 1153 (9th Cir. 2012). We also
    review de novo claims of ineffective assistance of counsel
    (“IAC”), which present mixed questions of law and fact.
    Rogers v. Dzurenda, 
    25 F.4th 1171
    , 1180 (9th Cir. 2022).
    Any factual findings made by the district court in evaluating
    IAC claims are reviewed for clear error. See 
    id.
     Because no
    state court reviewed Leeds’s IAC claim, there is no special
    deference under AEDPA. See 
    id. at 1181
    .
    Where, as here, a petitioner’s claim was procedurally
    defaulted in a state habeas proceeding, he must show that the
    default was excused in order for federal habeas review to
    occur. See Martinez, 
    566 U.S. at
    9–10 (explaining that
    federal courts will not review the merits of a claim “that a
    state court declined to hear because the prisoner failed to
    abide by a state procedural rule” unless an exception
    applies). In short, a petitioner can only “obtain federal
    review of a defaulted claim by showing cause for the default
    and prejudice from a violation of federal law.” 
    Id.
     at 10
    (citing Coleman v. 
    Thompson, 501
     U.S. 722, 750 (1991))
    (emphasis added).
    III.
    In Martinez, the Supreme Court recognized that attorney
    error can establish cause to excuse procedural default of a
    trial counsel IAC claim when the state requires a prisoner to
    raise that claim for the first time in post-conviction
    proceedings. 
    566 U.S. at
    11–12, 14; accord Shinn v.
    LEEDS V. RUSSELL                          13
    Ramirez, 
    142 S. Ct. 1718
    , 1733 (2022). 2 In states that
    maintain such a requirement, the state habeas court is the
    only court that will review the merits of a trial counsel IAC
    claim. If a prisoner does not have adequate counsel in the
    initial habeas proceeding, “[he] will have . . . difficulties
    vindicating a substantial [IAC] claim,” since he will be
    unable to “rely on a court opinion or the prior work of an
    attorney addressing that claim.” Martinez, 
    566 U.S. at
    11–
    12 (citing Halbert v. Michigan, 
    545 U.S. 605
    , 619 (2005)).
    Thus, to protect the prisoner’s “right to the effective
    assistance of counsel at trial,” Martinez held that an effective
    attorney is required in these initial-review collateral
    proceedings, and ineffective assistance by post-conviction
    counsel can establish cause for default. 
    Id.
     at 12–14.
    To show cause under Martinez, a petitioner must show
    that “counsel in the initial-review collateral proceeding,
    where the claim should have been raised, was ineffective
    under the standards of Strickland v. Washington.” Id. at 14.
    The Strickland standard requires the petitioner to show that
    (1) PCC’s performance was deficient, and (2) PCC’s
    deficient performance prejudiced the petitioner. Strickland,
    
    466 U.S. at 687
    . To show prejudice under Martinez, “a
    prisoner must also demonstrate that the underlying
    ineffective-assistance-of-trial-counsel claim is a substantial
    one, which is to say that the prisoner must demonstrate that
    the claim has some merit.” Martinez, 
    566 U.S. at 14
    .
    2
    Although the Supreme Court’s recent decision in Shinn narrowed the
    circumstances in which Martinez applies, that decision does not impact
    this case because no new evidence is required to evaluate Leeds’s
    claims. See Shinn, 142 S. Ct. at 1734 (“We now hold that, under
    § 2254(e)(2), a federal habeas court may not conduct an evidentiary
    hearing or otherwise consider evidence beyond the state-court record
    based on ineffective assistance of state postconviction counsel.”).
    14                    LEEDS V. RUSSELL
    Because a petitioner must demonstrate both cause and
    prejudice, courts can analyze the two requirements in any
    order. See, e.g., Michaels v. Davis, 
    51 F.4th 904
    , 931 (9th
    Cir. 2022) (addressing prejudice first); Djerf v. Ryan, 
    931 F.3d 870
    , 880–81 (9th Cir. 2019) (addressing only cause).
    “Although the cause and prejudice requirements are
    distinct, ‘there is considerable overlap between these
    requirements, since each considers the strength and validity
    of the underlying ineffective assistance claim.’” Michaels,
    51 F.4th at 931 (quoting Djerf, 931 F.3d at 880); see
    Dickinson v. Shinn, 
    2 F.4th 851
    , 858 n.3 (9th Cir. 2021)
    (explaining that evaluating the second Strickland prong
    during the Martinez cause analysis necessarily requires some
    showing of the strength of the underlying trial counsel IAC
    claim). Notably, the standard for evaluating the underlying
    trial counsel IAC claim during the Martinez prejudice
    analysis is not as stringent as that required when considering
    the merits of the underlying claim. See Michaels, 51 F.4th
    at 930 (“[A] conclusion on the merits of [a trial counsel IAC]
    claim under Strickland holds a petitioner to a higher burden
    than required in the Martinez procedural default context,
    which only requires a showing that the [trial counsel IAC]
    claim is ‘substantial.’”). Nonetheless, this “does not
    diminish the requirement . . . that petitioner satisfy the
    ‘prejudice’ prong under Strickland in establishing
    ineffective assistance by post-conviction counsel [during the
    Martinez cause analysis].” Clabourne v. Ryan, 
    745 F.3d 362
    , 377 (9th Cir. 2014) (emphasis added), overruled on
    other grounds by McKinney v. Ryan, 
    813 F.3d 798
     (9th Cir.
    2015) (en banc).
    Only when a federal court has determined that a
    procedural default is excused under Martinez can it turn to
    the merits of the underlying IAC claim. See Martinez, 566
    LEEDS V. RUSSELL                     15
    U.S. at 17 (“A finding of cause and prejudice does not entitle
    the prisoner to habeas relief. It merely allows a federal court
    to consider the merits of a claim that otherwise would have
    been procedurally defaulted.”); Michaels, 51 F.4th at 936.
    With this framework in mind, we review Leeds’s claim.
    IV.
    We first address Martinez’s prejudice prong to determine
    whether Leeds’s underlying trial counsel IAC claim is
    substantial. We then turn back to Martinez’s cause prong
    and evaluate whether Leeds’s PCC’s failure to raise a trial
    counsel IAC claim based on the burglary theory constituted
    ineffective assistance under Strickland. We conclude that
    Leeds has demonstrated both cause and prejudice, excusing
    his procedural default.
    A. Leeds’s Trial Counsel IAC Claim Is Substantial
    Under Martinez’s Prejudice Requirement
    “To establish ‘prejudice’ under Martinez, the underlying
    trial counsel IAC claim must also be ‘a substantial one,
    which is to say . . . that the claim has some merit.’”
    Michaels, 51 F.4th at 930–31 (quoting Martinez, 
    566 U.S. at 14
    ). The Supreme Court has said little about the meaning of
    “substantial,” but has cited as analogous the standard for
    granting a certificate of appealability under 
    28 U.S.C. § 2253
    . See Martinez, 
    566 U.S. at
    14 (citing Miller-El v.
    Cockrell, 
    537 U.S. 322
     (2003)). For a certificate of
    appealability to issue, a habeas petitioner must show “that
    reasonable jurists could debate whether the issue should
    have been resolved in a different manner or that the claim
    was adequate to deserve encouragement.” Apelt v. Ryan, 
    878 F.3d 800
    , 828 (9th Cir. 2017) (quotations omitted). Under
    that standard, “[a] court should conduct a ‘general
    16                    LEEDS V. RUSSELL
    assessment of the[] merits,’ but should not decline to issue a
    certificate ‘merely because it believes the applicant will not
    demonstrate an entitlement to relief.’” Cook v. Ryan, 
    688 F.3d 598
    , 610 n.13 (9th Cir. 2012) (alteration in original)
    (quoting Miller-El, 
    537 U.S. at
    336–37).
    Leeds’s underlying claim is that his trial counsel
    provided ineffective assistance by failing to argue that he
    could not burglarize his own home, which could have
    prevented the State from relying on the felony-murder rule
    as a basis for seeking a first-degree murder conviction. He
    argues that if the felony-murder rule had not been available,
    the State could not have shown beyond a reasonable doubt
    that he committed a willful, deliberate, and premeditated
    murder, and that he therefore could not have been convicted
    of first-degree murder. When considering whether trial
    counsel was ineffective, we again use the Strickland
    standard, though we do not apply it as strictly as if we were
    considering the merits of the claim. See Michaels, 51 F.4th
    at 930.
    1. Trial Counsel Performed Deficiently
    Under Strickland, “the proper standard for attorney
    performance is that of reasonably effective assistance.” 
    466 U.S. at 687
    . “When a convicted defendant complains of the
    ineffectiveness of counsel’s assistance, the defendant must
    show that counsel’s representation fell below an objective
    standard of reasonableness.” 
    Id.
     at 687–88. This standard
    means “simply reasonableness under prevailing professional
    norms.” 
    Id. at 688
    . That said, because it is easy to second-
    guess counsel’s assistance in hindsight, “a court must
    indulge a strong presumption that counsel’s conduct falls
    within the wide range of reasonable professional assistance.”
    
    Id. at 689
    . We “judge the reasonableness of counsel’s
    LEEDS V. RUSSELL                     17
    challenged conduct on the facts of the particular case,
    viewed as of the time of counsel’s conduct.” 
    Id. at 690
    .
    Here, the State argues that Leeds’s counsel could not
    have performed unreasonably by failing to argue in 2006 that
    a person could not burglarize his own home because the
    Nevada Supreme Court did not so rule until 2014. See
    White, 330 P.3d at 486. It is true that White constituted the
    first instance in which the court addressed that question, and
    the reasonableness standard does not require counsel to
    predict changes in the law.          See Sophanthavong v.
    Palmateer, 
    378 F.3d 859
    , 870 (9th Cir. 2004) (“Strickland
    does not mandate prescience, only objectively reasonable
    advice under prevailing professional norms.”). But just
    because the issue was not definitively decided until 2014
    does not mean it would have been reasonable for a defense
    attorney not to make the burglary theory argument before
    that date. As the Nevada Supreme Court explained in White,
    Nevada’s burglary statute is subject to two
    reasonable interpretations: (1) the Legislature
    intended to revoke the common law rule that
    burglary requires entry into the building of
    another, or (2) the Legislature incorporated
    the common law requirement by failing to
    expressly include one’s own home as a
    possible place of burglary.
    330 P.3d at 484.
    Because Nevada’s burglary statute was susceptible to
    two interpretations, a reasonable counsel would have argued
    for the interpretation that would preclude her client from
    facing a felony-murder charge. In concluding that “one
    cannot burglarize his own home so long as he has an absolute
    18                        LEEDS V. RUSSELL
    right to enter the home,” id. at 485–86, the White court
    considered the purposes of common law burglary, the
    legislative intent of Nevada’s burglary statute, and
    California’s approach to the issue. Id. at 485. These
    arguments were available before White, and it does not take
    the benefit of hindsight to realize the obvious strength of the
    approach. 3
    The Nevada Supreme Court confirmed as much in Weber
    v. State, 
    132 Nev. 1043
    , 
    2016 WL 3524627
     (Nev. 2016)
    (unpublished disposition).      There, with an excellent
    perspective to evaluate professional standards for defense
    counsel in that state, the Nevada Supreme Court allowed a
    petitioner to go forward with the claim that his trial counsel
    was ineffective because he failed to argue that the petitioner
    could not have burglarized his own home even though the
    counsel’s representation took place before White was
    decided. 
    Id. at *12
    . The Nevada Supreme Court explained:
    “As White merely articulated the substantive law on burglary
    as it has always been in Nevada, appellate counsel could
    have challenged the burglary convictions and felony
    aggravating circumstance [before White was decided].” 
    Id.
    The burglary theory argument was also not far-fetched.
    Nevada precedent supported the argument. In 1959, for
    example, the Nevada Supreme Court explained that while
    the codification of the Penal Code altered some elements of
    common law crimes, the “common-law definition of
    burglary is breaking and entering the dwelling house of
    3
    Indeed, Leeds’s counsel understood that felony murder was easier for
    the State to prove than premeditation. She argued that the State should
    not be able to rely on the felony-murder rule, though she did not argue
    that it was inapplicable because Leeds could not burglarize his own
    home.
    LEEDS V. RUSSELL                      19
    another,” and while the legislature can alter a definition, “in
    legislating on crimes the definitions of which have been so
    well and commonly understood as the crime[] of
    burglary . . . , the substitution will not be presumed unless
    the intention is manifest.” Smith v. First Jud. Dist. Ct., 
    347 P.2d 526
    , 528–29 (Nev. 1959) (quoting State v. Petit, 
    72 P. 1021
    , 1022 (1903)). While the Nevada legislature may have
    “expanded common law burglary in several respects, it has
    at least retained the notion that . . . one cannot burglarize his
    own home so long as he has an absolute right to enter the
    home.” White, 330 P.3d at 486.
    The laws of states with similar burglary statutes also
    supported the burglary theory argument. In 1975, the
    California Supreme Court established that a person cannot
    burglarize his own home. See People v. Gauze, 
    542 P.2d 1365
    , 1367 (Cal. 1975). The California court considered the
    California burglary statute, which is nearly identical to
    Nevada’s statute, and concluded that—while there were two
    reasonable interpretations—the purpose underlying
    common law burglary (i.e., protection of one’s own home
    from invasion) was not altered by the enactment of the Penal
    Code. 
    Id.
     at 1366–67. Leeds’s counsel could have looked
    to California’s clear law, as the Nevada Supreme Court did
    in White. See 330 P.3d at 484–86; see also Hobbs v. State,
    
    251 P.3d 177
    , 179–80 (Nev. 2011) (considering California’s
    caselaw interpreting its battery statute to interpret Nevada’s
    similar statute).
    Leeds’s counsel was “obliged to make, or at least to
    evaluate, an argument that [wa]s sufficiently foreshadowed
    in existing case law.” Bridges v. United States, 
    991 F.3d 793
    , 804 (7th Cir. 2021). Because Nevada law could always
    have reasonably been interpreted to mean a person could not
    burglarize his own home (as the Nevada Supreme Court
    20                     LEEDS V. RUSSELL
    concluded in Weber), competent counsel would have been
    expected to make that argument.
    2. Trial    Counsel’s       Deficient      Performance
    Prejudiced Leeds
    Because Leeds has made a strong showing that his trial
    counsel performed deficiently, we next ask whether that
    deficient performance prejudiced Leeds. In other words,
    “the question is whether there is a reasonable probability
    that, absent the errors, the factfinder would have had a
    reasonable doubt respecting guilt.” Strickland, 
    466 U.S. at 695
    . Here, the State argues that even if Leeds’s counsel
    performed deficiently by failing to raise the burglary theory,
    Leeds was not prejudiced for two reasons. First, the State
    argues that Leeds cannot show that he had an unconditional
    right to enter the Evening Song house, so he could have
    burglarized the house and been found guilty of first-degree
    murder under the felony-murder theory. Second, the State
    argues that because there was overwhelming evidence that
    the murder was willful, deliberate, and premeditated, a jury
    would have found Leeds guilty of first-degree murder under
    that theory alone.
    We review the district court’s factual finding that Leeds
    had “a right to enter the [Evening Song] home as a joint
    occupant” for clear error. See Earp v. Davis, 
    881 F.3d 1135
    ,
    1142 (9th Cir. 2018). The State challenges this finding by
    arguing that there are three possible times at which Leeds
    did not have an unconditional right to enter. First, it argues
    that Leeds never had an unconditional right to enter the
    Evening Song house. Second, it argues that he “moved out
    of the house on Wednesday,” three days before the murder.
    Third, it argues that after Leeds was escorted off the property
    by the police on Friday night (twelve hours before the
    LEEDS V. RUSSELL                     21
    murder) and voluntarily took his remaining personal
    belongings, any expectation he had of returning had been
    extinguished.
    All three arguments are unavailing. Leeds clearly lived
    in the Evening Song house with Lane from the time they
    moved in. It is true that Leeds was not listed on the lease,
    did not pay rent, and did not have a key to the house. But
    while these facts may be relevant considerations, they do not
    entirely determine whether Leeds had a right to enter the
    home. Cf. White, 330 P.3d at 486 (“[W]hile ownership may
    be one factor to consider, the appropriate question is whether
    the alleged burglar has an absolute, unconditional right to
    enter the home.”). Lane testified multiple times that Leeds
    lived at the house with her, that he did not need a key because
    the back door was always open, and that it was never their
    plan for Leeds to pay rent. She never testified that there was
    any issue with their living arrangements, beyond her few
    suggestions that he get a place of his own. When Leeds left
    on Wednesday for the Thanksgiving holiday, both he and
    Lane understood the situation to be temporary. A temporary
    exit does not terminate an occupant’s absolute right to enter.
    See id. at 486 (“Even though [defendant] orally agreed to
    stay elsewhere during the week, he still maintained an
    absolute right to enter the residence.”).
    Leeds also did not give up his status as an occupant on
    the night before the murder. Although the State argues
    Leeds was “escorted off the property by the police” and that
    he “voluntarily took all of his remaining personal belongings
    with him,” this argument misstates the record. The police
    told Lane that Leeds had a right to stay at the house because
    he had been living there and she would need to evict him.
    Leeds voluntarily went with the police to cool off. Nor did
    Leeds collect all his property. He took his yoga mat and
    22                     LEEDS V. RUSSELL
    laptop, but his other belongings remained at the house and in
    the garage. The cases on which the State relies to argue
    Leeds instantaneously gave up his occupancy are inapposite.
    In both Sears and Ulloa, the defendants had fully separated
    from their wives and permanently moved out of the homes
    in question (for four months in Ulloa and for three weeks in
    Sears). See People v. Sears, 
    401 P.2d 938
    , 944 (Cal. 1965),
    overruled on other grounds by People v. Cahill, 
    853 P.2d 1037
    , 1059 n.17 (Cal. 1993); People v. Ulloa, 
    102 Cal. Rptr. 3d 743
    , 745 (Cal. Ct. App. 2009). Lane and Leeds had never
    fully separated, and Leeds had never moved out. The district
    court did not err when it assessed these facts to conclude that
    Leeds had an unconditional right to enter the Evening Song
    house.
    We next consider the State’s argument that there was
    overwhelming evidence that the murder was willful,
    deliberate, and premeditated. We review this contention de
    novo. Although the State presented evidence to support its
    premeditation theory, Leeds countered this theory by
    arguing that the case was about manslaughter. His counsel
    pointed to record evidence suggesting a self-defense or heat-
    of-passion killing. Because the jury had to reach a
    unanimous verdict and the evidence towards any single
    theory was not overwhelming, the district court correctly
    concluded that a reasonable juror could have believed that
    Leeds acted in the heat-of-passion or that the State had not
    proved the premeditation theory beyond a reasonable doubt.
    It is thus possible that the outcome of the trial would
    have been different if trial counsel had raised the burglary
    theory to preclude the use of the felony-murder rule. Instead,
    the jury was instructed on both the felony-murder theory and
    the willful, deliberate, and premeditated theory. In closing
    argument, the State explicitly told the jury: “You don’t have
    LEEDS V. RUSSELL                      23
    to agree on the theory. Remember, there’s two theories
    that’ll get you to first degree murder in this case.” The
    general verdict form does not tell us which theory each juror
    relied upon, but we do know that the jury found Leeds guilty
    of burglary, rendering it possible that at least one juror relied
    on the felony-murder theory to find him guilty of first-degree
    murder. Because the verdict must be unanimous, the
    outcome of Leeds’s trial could have been different if only
    “one juror would have struck a different balance.” Wiggins
    v. Smith, 
    539 U.S. 510
    , 537 (2003). We find it likely that, if
    the trial court had declined to instruct the jury on the felony-
    murder theory, at least one juror may have not been
    convinced beyond a reasonable doubt that Leeds—
    distraught after discovering that his partner of twenty years
    was moving on—committed a willful, deliberate, and
    premeditated murder.
    Leeds has thus shown that his trial counsel IAC claim is
    substantial. In other words, the claim has “some merit” and
    therefore satisfies Martinez’s prejudice requirement.
    B. Leeds’s PCC Provided Ineffective Assistance Under
    Strickland, Meeting the Martinez Cause Requirement
    To show “cause” for his procedural default, Leeds must
    demonstrate that, in failing to raise an IAC claim based on
    trial counsel’s failure to assert the burglary theory, PCC was
    ineffective under the Strickland standard. Martinez, 
    566 U.S. at 14
    . Strickland requires Leeds to show that (1) PCC’s
    performance was deficient, and (2) PCC’s deficient
    performance prejudiced Leeds. Strickland, 
    466 U.S. at 687
    .
    While we reviewed trial counsel’s actions in our Martinez
    prejudice analysis under a more relaxed standard, see
    Michaels, 51 F.4th at 930, we apply the Strickland standard
    24                    LEEDS V. RUSSELL
    with full force when considering PCC’s actions in the
    Martinez cause analysis. See Clabourne, 
    745 F.3d at 377
    .
    1. PCC Performed Deficiently
    Again, the State argues that Leeds’s PCC could not have
    performed deficiently in 2013 because White was not
    decided until 2014. See White, 330 P.3d at 486. For the
    same reasons we explained above, we reject this argument.
    Although we evaluate PCC’s actions more stringently than
    we evaluated trial counsel’s actions, see Clabourne, 
    745 F.3d at 377
    , our earlier analysis leads us to conclude that
    PCC’s “representation fell below an objective standard of
    reasonableness.” Strickland, 
    466 U.S. at
    687–88. We do not
    “second-guess counsel’s assistance” in hindsight, 
    id. at 689
    ,
    but rather recognize that it was unreasonable not to present
    an argument that could have prevented the State from relying
    on the felony-murder theory to obtain a first-degree murder
    conviction.
    As the Nevada Supreme Court explained, “White merely
    articulated the substantive law on burglary as it has always
    been in Nevada.” Weber, 
    2016 WL 3524627
    , at *12
    (explaining that appellate counsel “could have” challenged
    the burglary conviction before White, and PCC might have
    performed unreasonably by failing to raise an IAC claim on
    that basis). Just as trial counsel could have made the
    burglary theory argument in 2006, PCC could have made the
    argument in 2013 by relying on a common understanding of
    the definition of “burglary,” basic statutory interpretation
    principles, and the law of other states with similar criminal
    statutes. The failure to do so was unreasonable. As we noted
    above, counsel perform deficiently when they fail to “make,
    or at least to evaluate, an argument that is sufficiently
    LEEDS V. RUSSELL                     25
    foreshadowed in existing case law.” Bridges, 991 F.3d at
    804.
    While PCC filed a 60-page habeas petition that identified
    many claims of error at the trial level, the thoroughness of
    the petition does not negate PCC’s failure to recognize a
    potentially dispositive claim. With felony-murder on the
    table, the State only had to prove that Leeds committed
    burglary, a much easier task than proving—beyond a
    reasonable doubt—that Leeds committed a willful,
    deliberate, and premeditated murder. Given those stakes,
    trial counsel provided ineffective assistance by failing to
    make the burglary theory argument, and PCC performed
    deficiently by failing to recognize that error. See Michaels,
    51 F.4th at 934 (“Had PC[C] performed adequately, they
    would have recognized trial counsel’s conduct amounted to
    ineffective assistance and raised the IAC claim in the first
    habeas petition.”).
    As the record shows, PCC did not raise the burglary
    theory until White was decided, although the argument was
    always available. Given the importance of the burglary
    theory argument to Leeds’s case, counsel’s failure was
    substantial. In short, a “failure to recognize a potentially
    viable IAC claim is not a strategic decision.” Michaels, 
    51 F.4th 935
    . We therefore affirm the district court’s finding
    that Leeds’s PCC performed deficiently because a
    reasonably competent post-conviction counsel would have
    recognized the trial counsel’s error in failing to advance the
    burglary theory argument.
    2. PCC’s Deficient Performance Prejudiced Leeds
    Having concluded that PCC’s performance was
    deficient, we consider Leeds’s argument that this deficient
    performance prejudiced him, thereby meeting the second
    26                     LEEDS V. RUSSELL
    Strickland prong and showing cause under Martinez. See
    Martinez, 
    566 U.S. at 14
    ; Strickland, 
    466 U.S. at 691
    . To
    show prejudice, a petitioner “must show that there is a
    reasonable probability that, but for counsel’s unprofessional
    errors, the result of the proceeding would have been
    different. A reasonable probability is a probability sufficient
    to undermine confidence in the outcome.” Strickland, 
    466 U.S. at 694
    . Moreover, the “question is not whether the
    particular [post-conviction review] court would have
    rendered a more favorable decision, but whether some
    reasonable [post-conviction review] court might have done
    so.” Michaels, 51 F.4th at 935 (citing Apelt, 
    878 F.3d 827
    ).
    Leeds must show that, if PCC had raised an IAC claim based
    on trial counsel’s failure to argue the burglary theory, a
    reasonable Nevada court could have granted his post-
    conviction petition.
    “Whether PC[C]’s ineffectiveness prejudiced [Leeds]
    depends in part on the strength of his underlying trial counsel
    IAC claim, Djerf, 931 F.3d at 880, and in part on the use
    PC[C] could have made of that claim had it been properly
    raised in the state habeas petition.” Michaels, 51 F.4th at
    935; see also Dickinson, 2 F.4th at 858. If the underlying
    IAC claim were meritless, PCC “would not be ineffective for
    failure to raise an [IAC] claim with respect to trial counsel
    who was not constitutionally ineffective.” Sexton, 
    679 F.3d at 1157
    . As discussed above, Leeds’s trial counsel IAC
    claim is substantial. The underlying claim here is strong,
    because—since Leeds was found guilty of burglary and the
    evidence of premeditated murder was not overwhelming—it
    is likely that some jurors found Leeds guilty of first-degree
    murder by relying on the felony-murder theory. If the
    felony-murder theory had not been available to the jurors,
    Leeds may not have been convicted of first-degree murder
    LEEDS V. RUSSELL                     27
    at all. Thus, if trial counsel had recognized and asserted the
    burglary theory, the outcome of Leeds’s trial may have been
    different.
    Given the strength of the underlying claim, it is likely
    that PCC would have been able to rely on the IAC claim to
    persuade a post-conviction review court that Leeds was
    denied effective assistance when his trial counsel failed to
    assert the burglary theory and thereby allowed the State to
    prove its case under the easier felony-murder theory. Any
    reasonable court would have seen the strength of the
    burglary theory argument and its potential to avoid a first-
    degree murder conviction. There is thus “a reasonable
    probability that . . . the result of the [post-conviction]
    proceeding would have been different” if PCC had not failed
    to allege an IAC claim based on the burglary theory. See
    Strickland, 
    466 U.S. at 694
    . Indeed, the “likelihood of a
    different result [is] substantial, not just conceivable.”
    Harrington v. Richter, 
    562 U.S. 86
    , 112 (2011) (describing
    the Strickland prejudice standard).
    In sum, we conclude that it is reasonably probable that a
    Nevada court would have granted Leeds’s post-conviction
    petition if PCC had properly asserted Ground Two. It is not
    lost on us that Nevada’s Supreme Court has already
    recognized a willingness to hear such claims. See Weber,
    
    2016 WL 3524627
    . We thus conclude that PCC’s failure to
    assert an IAC claim based on the burglary theory prejudiced
    Leeds. Leeds has demonstrated that his PCC was ineffective
    under Strickland, meeting Martinez’s cause requirement.
    Because we conclude that Leeds has demonstrated cause
    and prejudice under Martinez, we affirm the district court’s
    conclusion to excuse the procedural default of Ground Two.
    28                    LEEDS V. RUSSELL
    V.
    After the district court concluded that Leeds’s procedural
    default was excused, it reached the merits of Leeds’s trial
    counsel IAC claim. See Martinez, 
    566 U.S. at 17
     (explaining
    that courts consider the merits of a claim only after excusing
    procedural default). The court applied Strickland, concluded
    that Leeds’s claim was successful, and granted habeas relief.
    It is not entirely clear whether the State challenges the
    district court’s decision on the merits of Leeds’s IAC claim.
    The State’s briefing focuses primarily on the district court’s
    finding of prejudice, both during the Strickland analysis in
    the Martinez cause prong and in the Martinez prejudice
    analysis. Nonetheless, we construe the State’s argument as
    also challenging the district court’s merits determination.
    We affirm. To succeed on his IAC claim, Leeds was
    required to prove: “(1) that his counsel’s performance fell
    below an objective standard of reasonableness (the deficient
    performance prong); and (2) that there is a reasonable
    probability of a more favorable outcome if counsel
    performed effectively (the prejudice prong).” Rogers, 25
    F.4th at 1181 (citing Strickland, 
    466 U.S. at
    687–88). As we
    have repeatedly discussed above, the burglary argument was
    always available to counsel. Had counsel raised the burglary
    argument, it is reasonably probable that the trial court would
    not have allowed the State to rely on the felony-murder
    theory as a basis for a first-degree murder conviction. Trial
    counsel’s failure to raise this objectively important argument
    constituted deficient performance.
    We cannot determine whether the jury (or any juror)
    relied on the felony-murder theory or the willful, deliberate,
    and premeditated theory to convict Leeds of first-degree
    murder, but we know the jury found him guilty of burglary.
    LEEDS V. RUSSELL                      29
    See Yates, 
    354 U.S. at 312
     (a verdict should be set aside “in
    cases where the verdict is supportable on one ground, but not
    on another, and it is impossible to tell which ground the jury
    selected”). It is probable that at least one juror relied on the
    felony-murder theory. Because the outcome of the trial
    would have been different if even “one juror would have
    struck a different balance,” Wiggins, 
    539 U.S. at 537
    , “there
    is a reasonable probability that . . . the result of the
    proceeding would have been different” without the use of the
    felony-murder rule. Strickland, 
    466 U.S. at 694
    . Trial
    counsel’s deficient performance thus prejudiced Leeds. The
    district court therefore did not err in granting him habeas
    relief.
    VI.
    For the foregoing reasons, we affirm the district court’s
    judgment to excuse the procedural default and grant Leeds’s
    habeas petition on the basis of Ground Two.
    AFFIRMED.
