5. Spinda
It's a gimmick, and besides Contrary is given to way better Pokemon. It's useless outside of Contrary.
Name 5 Pokemon that if you remove at least one attack from their movepool, they would be worse/would suck. (Only applies to competitive play, not in-game)
(And even though I think that it would be cheating, I will post the 1st one)
1. Lilligant (Removing Quiver Dance). It's movepool is generic Grass-type aside from that (And also Dream Eater and Healing Wish), and removing Quiver Dance removes anything that makes it good/usable in Wi-Fi battles. (Sorry for dissing you buddy, but I had to say it) Though I have to admit, in Rom Hacks Lily without QD is decent. And I also like using it in Pokemon X, though it doesn't have it. (After-game, of course)
