sorry for the delay i got very sleepy last night
second slash jolly after adamant, it's very nice to guaranteed outpace stuff like groudon, scarfless kyogre, defensive yveltal, zekrom, at worst tie lunala, et al. the part about "muscling past defensive pokemon like...zygarde" is misleading cause u actually fuckin lose to defensive zygarde if it's already big by the time you come in (252+ Atk Choice Band Urshifu Wicked Blow vs. 208 HP / 244+ Def Zygarde-Complete on a critical hit: 205-243 (32.8 - 38.8%) -- 6.3% chance to 3HKO after Leftovers recovery and you just get glared). replace zygarde with a different defensive mon like sdef eternatus, which does actually lose if it tries to switch in (252+ Atk Choice Band Urshifu Wicked Blow vs. 240 HP / 0 Def Eternatus on a critical hit: 337-397 (70 - 82.5%) -- guaranteed 2HKO after Black Sludge recovery). not in love with "close combat targets dark types like yveltal" cause defensive yveltal cant actually do shit back (252+ Atk Dark Aura Yveltal Foul Play vs. 0 HP / 0 Def Urshifu: 56-66 (16.4 - 19.3%) -- possible 6HKO) and you 2hko it with wicked blow with adamant/are probably faster if ur jolly (252+ Atk Choice Band Urshifu Wicked Blow vs. 248 HP / 4 Def Dark Aura Yveltal on a critical hit: 222-261 (48.7 - 57.3%) -- 94.9% chance to 2HKO), (252 Atk Choice Band Urshifu Wicked Blow vs. 248 HP / 4 Def Dark Aura Yveltal on a critical hit: 203-239 (44.6 - 52.5%) -- 21.5% chance to 2HKO). the thing is that close combat doesnt have that many legit targets cause 90% of the time this thing clicks wicked blow or u-turn and 8% it's clicking sucker punch; you can really just leave it at other urshifu and ttar as targets cause theres fuckall else. you say sucker punch is there to revenge kill "faster pokemon like kyogre," but urshifu should be faster than kyogre unless it's scarfed or theyre banking on you not being jolly. it also does less than half to groudon and u get boned if it just SDs on u. i would change the ogre mention in the sucker punch part to scarf + remove groudon mention there; you could say sucker RKs cb marshadow instead of rp don (which it does: 252+ Atk Choice Band Urshifu Sucker Punch vs. 0 HP / 4 Def Marshadow: 226-267 (70.4 - 83.1%) -- guaranteed 2HKO. necrozma/ho-oh teammate mentions are a bit boring but fine, although i woudn't say whirlwind really "threatens" fairies (really just phazes geoxern) so you can mention a different thing ho-oh does instead, like twaving or toxicing them. also, in the part where you explain why it has max atk you also need to explain why it has max speed (which you can do in as much or less space than the atk explanation).
implement this stuff and then u have my stamp of approval
