i have yet to encounter more than one Mega Khan that carries crunch on PS, or on DS. It's just not common. Every time i have switched my Def Dusclops into it, taken a normal type move, burned it, then comfortably out stall or switch. with DUSCLOPS of all things, DUSCLOPS (i make this point because you guys say it sucks, so i am countering it with a sucky mon, therefore, based on this communities logic, Khan should not be quickbanned.) While crunch will easily become a more common move and i won't be able to outstall it anymore, for now it works. Even with crunch, it still whiffed return on Dusclops, and i burned it. The most common set i see is
Fake Out, PUP, Sucker Punch, and Return. Thats it. I have only encountered one Crunch Khan, and it didn't have earthquake or PUP, so i ferrothorned it to death.
