doesn't heavy offense just abuse ambipom's fake out and technotop as well as like 2 sucker punchers
Ambipom and Technotop Fake Out are useless thanks to Protect. Yanmega can easily take a Hitmontop Bullet Punch/Sucker Punch also, even after Stealth Rock.
EDIT: The post above me makes no sense whatsoever ._. Yanmega doesn't need or particularly enjoy Wish support any more then anything else. And it's defences aren't exactly high, only enough to take one (or two if SR isn't down) strong priority moves just fine.
Dugtrio in UU really does face problems, as the big thing it had in OU was the ability to OHKO the ridiculously popular ScarfTran. In UU, it has no particular utility, and thus suffers an even larger loss in usage.
Lol. I seriously, seriously, hope you're kidding. How can you even say that after reading pretty much any comment in this thread about yanmega/registeel? The thing is extremely usefull in UU as it traps pokemon that give pretty much any teams a shitload of problems(registeel, chansey, blaziken, roserade, etc.). Why you would say that outside of it being a joke or sarcasm is beyond me.
Well, considering that I play UU, I'm not joking. While I never denied that Dugtrio has its uses in UU, I'm just pointing out that in OU, it can trap and get a OHKO on the fourth most popular Pokemon in OU is a pretty big thing. It is O.K. in UU, but it just doesnt posess the utility that it did in OU.
