File this one under least likely to be included, but Chandelure is really joining Pokken Tournament as a playable character.
The full roster so far is Charizard, Pikachu, Pika Libre, Machamp, Gengar, Mewtwo, Suicine, Sceptile, Blaziken, Gardevoir, Garchomp, Lucario, Weavile, Braxien, Shadow Mewtwo, and no Chandelure.
