yeah getting rid of heatran is huge and earthquake KOs all but the defensive version, and i like the switch back to hp fire because honestly getting walled by scizor or walled and paralyzed by jirachi sucks, especially now that i use donphan to switch in vs dragons anyway, 2HKO on dragonite and that means it cant boost enough to outspeed charizard who still has hp ice. right now im using earthquake hp fire giga drain and growth
