I just wish the roster was wider in this game. Right now, it stands at eight playable Pokemon: Blaziken, Snorlax, Gengar, Lucario, Gardevoir, Breloom, Combusken, and Swalot. This is a pretty good roster (made better if you factor in their assists), although I would've replaced Combusken with another Pokemon (either a Water-type of some kind or maybe Staraptor). Might be kind of neat to throw in a few more monsters (at least four more). Maybe...
Dawn's Mamoswine (with Piplup, Pachirisu, and Cyndaquil as assists),
Cyrus's Honchkrow (Purugly, Skuntank, and Toxicroak),
Cynthia's Garchomp (with Milotic, Spiritomb, and Togekiss assists),
and a Zoroark (assisted by Snivy, Tepig, and Oshawott) to represent Unova.
