Wally.

Search your deck for a card that evolves from 1 of your Pokémon (excluding Pokémon-EX) and put it onto that Pokémon. (This counts as evolving that Pokémon.) Shuffle your deck afterward. You can use this card during your first turn or on a Pokémon that was put into play this turn.

You may play only 1 Supporter card during your turn (before your attack).
