On the topic of moves/animations, I think Ike needs a different Up-Throw, it doesn't look good seeing him leave his sword stuck in the ground super-quickly, and then have it almost appear in his hand from thin air once he's done. It's especially noticeable when people chain Up-throws together.
And maybe I'm just biased, but I really don't like Ike's Up-Air. It doesn't make sense that twirling a sword above your head can hurt somebody..
Also, maybe there should be new Vegetable models for some of Peach's weaker turnips?
