Could be a Zoroark or Ditto. Or very well a typo since it shows Ash Unfezant as a Male, he shows 7 pokemon when we know Ash is using Pikachu so obviously one shown won't battle.
And the evolution part is very true considering instances such as Politoed evolving from just contact with Kings Rock. Either way I'd love to see our first sixth gen here. But I don't get the feeling we will for some reason.
