252 Atk Choice Band Golem Stone Edge vs. 0 HP / 4 Def Tomohawk: 252-297 (71.7 - 84.6%) -- guaranteed 2HKO
Well, I hate to say this, but it works. Tomo roosts up, Stone edge only does half of above calc afterwards, and eventually, either stone edge runs out of PP or tomo gets off two earth powers and wins
