>>30062835loads of setup options to be good, but none of which he can do better than say, Dragonite or Hydreigon.
DDance is probably his most reliable set, he'll be faster and a little bulkier than Dragonite, but doesn't have the setup potential that multiscale gives Dragonite.
He can also run a mean choice specs set on the special side, but the speed is more of an issue here.
Belly Drum is your big high risk/ultimate reward set, if you're a betting man go for it.
I'll stick to Ddance though, between 2 STAB's and poison jab for fairy coverage, he does the job well enough to warrant use on a serious team.
