I would much rather have Victini. I wouldn't mind Pokemon being an etrememly fickle series. Only holding onto Pikachu, Jigglypuff, and the idea of a Pokemon trainer. (I personally like the idea of a second gen PT) I think it's a cool idea to keep three slots free:
Pikachu
Jigglypuff
*New Pokemon trainer
*A Popular Pokemon
*Latest Gen Pokemon
Oh, and I recently read some stuff about Meowth's Party, it seems it was nothing more than an underwhelming Tech Demo. It might have become a game if it wasn't for A lot of other games (Like Loz, and Metroid) being majorly well recieved that year.
@Omega,
While I like like how you really decided to go unique with your PT choice, I think the Pokemon themselves are just really poor choices. I have nothing against Giovanni, he's alright enough, and would be a cool boss, but I think Silver has a much better chance at getting into Smash than Gio. (And even Silver has a low chance)
