I saw some promo cards up on ebay for MR:Evo and one of them has Moo's picture. Naturally this got my hopes up but I don't see him listed anywhere. Can anybody confirm whether or not he's in the game before I think of buying it?

Moo is in the game however Moo is so far not playable but you do fight the dragon at one point of the game.

as a slight spoiler you actually get to fight him twice. Where the second time is I won't say because its elsewhere on the site and i don't want to spoil the location if you want to get there on your own
