I should have gone to bed but instead did this. It's another one with fun incineroar math:
Mew @ Maranga Berry
Ability: Synchronize
EVs: 252 Def / 252 SpA / 4 SpD
Bold Nature
- Charm
- Earth Power
- Nasty Plot
- Ice Beam
Avalugg: earth power twice
252 SpA Mew Earth Power vs. 8 HP / 0- SpD Avalugg: 168-198 (50.4 - 59.4%)
252 Atk Choice Band Avalugg Icicle Spear (5 hits) vs. 0 HP / 252+ Def Mew: 210-245 (61.5 - 71.8%)
Goodra: np into two ice beams. Maranga berry saves you (253 times out of 256) from acid spray->draco. The 4 Spdef comes in handy by removing two possibilities here. mew has 341 hp for reference here, so goodra needs max roll draco plus top 3 roll on acid spray.
+2 252 SpA Mew Ice Beam vs. 248 HP / 0+ SpD Goodra: 210-248 (54.8 - 64.7%)
124 SpA Goodra Acid Spray vs. 0 HP / 0 SpD Mew: 35-42 (10.2 - 12.3%)
Possible damage amounts: (35, 36, 36, 36, 37, 37, 38, 38, 39, 39, 39, 40, 40, 41, 41, 42)
124 SpA Goodra Draco Meteor vs. -1 0 HP / 4 SpD Mew: 255-300 (74.7 - 87.9%)
Possible damage amounts: (255, 258, 261, 264, 267, 270, 273, 276, 279, 282, 285, 288, 291, 294, 297, 300)
Incineroar: charm->earth power spam.
252 SpA Mew Earth Power vs. 152 HP / 0 SpD Incineroar: 180-212 (48.7 - 57.4%) -- 94.1% chance to 2HKO
104+ Atk Incineroar Fake Out vs. 0 HP / 252+ Def Mew: 28-34 (8.2 - 9.9%)
Possible damage amounts: (28, 29, 29, 29, 30, 30, 30, 31, 31, 31, 32, 32, 32, 33, 33, 34)
-2 104+ Atk Incineroar Darkest Lariat vs. 0 HP / 252+ Def Mew: 90-108 (26.3 - 31.6%)
Possible damage amounts: (90, 90, 92, 92, 96, 96, 96, 98, 98, 98, 102, 102, 102, 104, 104, 108)
It's super unlikely but incineroar can technically win this by dodging the earth power 2hko and getting high rolls on all of its attacks. I'd do the math now but I've got physics in 8 1/2 hours and want to sleep. It's probably like less than one % though.
