I've been having LOADS of fun with Freeze Dry. At first I tried Articuno so I could take advantage of Hurricane too, but I've come to the conclusion that Cryogonal is the best user as it has the Speed to compete in OU. Simple, but the set I've been using is Timid 252 sp att/speed: freeze dry, iron defense, rapid spin, recover. You don't have great move coverage, but understandably, this Pokemon fills a particular niche as a Spinner, can tank a sp attack, outspeeds Garchomp, and can KO Gyarados and 2HKO RotomW. Don't expect to be sweeping, but when the time is right, Freeze Dry can be a nasty burn to an unsuspecting Water type.
