As stated, squirtle is the obvious choice, his speed and size make it very difficult to camp him with our projectiles and his air game rivals ours, heck its probably better. Ivy wouldnt be good for a few reasons, one of which being that toon's off the stage game is amazing and he has a easy time gimping, ivy is easily gimped already. We out camp him easily and im not positive, but dont bombs deal extra damage because of the fire thing? Charizard woldnt be a good choice because he is huge which makes him easy to hit with...well everything, but his rock is amazing.
