Something that people are overlooking is Gorebyss/Huntail's access to Baton Pass...
OH MAN!, I was almost sure none of those could get Baton Pass, I completely forgot about Huntail/Gorebyss! Idk how I would use it, I'd have to think about it, but good to know! =D
Imagine using Shell Break with Huntail, then substitute, then Rain Dance, speed then doubles, It also learns Ice Fang, that could be a nasty Dragon and/or Ground killer sweeper.
