Defensive and Swords Dance probably could be moved into one set: Tank. However, so many moves are theoretically perfectly viable for such a set (EQ, Taunt, Roost, Toxic, U-Turn, Facade, Stealth Rock, Protect, Ice Fang, Swords Dance, etc) that it's simply have to many slashes. I mean theoretically it could work, but I'd rather keep SD seperate, if only for aesthetic reasons.
