Just gonna leave this here:
252+ Atk Choice Band Abomasnow Wood Hammer vs. 252 HP / 4 Def Tangrowth in Grassy Terrain: 199-234 (49.2 - 57.9%) -- 59.8% chance to 2HKO after Grassy Terrain recovery
252+ Atk Choice Band Abomasnow Play Rough vs. 252 HP / 4 Def Tangrowth: 199-235 (49.2 - 58.1%) -- 62.9% chance to 2HKO after Grassy Terrain recovery
Yes, this even accounts for STAB on Play Rough...
That being said, being able to kill Dnite, Latias (already OHKO's Latios lmao), Guzzlord even, woulda been neat. But realistically, slapping a band and clicking Wood Hammer is usually just as effective.
