I don't know, I think Charizard is going to and up being a bowser-type character or something, and Squirtel about as useful as Doc. Ivysaur is probably going to be as useful as Yoshi or Kirby. I'm not complaining though, I love all of em.I like the stamina thing because it does eliminate the possibility of another Sheik problem. If you really like using Squirtle, then you're just gonna have to deal with Ivysaur and Charizard. That's one of PT's cons. Ideally though, all the pokemon will be useful anyway.
And if the Final Smash is Mewtwo, I think it would be hilarious if it was the same Mewtwo from Melee....
Almost better NOT to get the FS then...
EDIT: oh, and I think stamina's just going to be something like they do less damage when they're tired, like how in the other Smash Bros, if you keep doing the same move it does less damage.
