Also note that not everyone will include Quiver Dance in their movepool. Keeping Calm Mind is definitely the way to go in order to preserve the different visions of different movepool creators. I would post more thoroughly, but jas and Korski have pretty much summed up my thoughts. I'm definitely against Quiver Dance and I think it would bring too many similarities to Volcarona, which isn't conducive to learning much. It's not a move that it needs in any particular way either, so I'm for disallowing it. Dragon Dance, on the other hand, is something new, particularly with bluffing OU Dragons with Illusion; I am for it. Disallowing Substitute makes a lot of sense as well. I don't buy the argument of "CAP4 has better moves to use" at all. Pretty much every Pokemon develops a solid Substitute set sooner or later. If we include it, it will get used.
