There's no freaking way you're going to give a pokemon that high of a special attack stat without some sort of drawback. Slaking has Truant and Rampardos has terrible defensive tying and bad speed. And speaking of speed, 215 speed is SUPER unrealistic. Try to avoid power creep if you can, okay?
Also, WarpSpeed is broken. It's like Explosion, except guaranteed to destroy, no matter what the opponent does to stop it.
It is possible to make cool pokemon and moves without them being totally broken, if you can believe it.
