PichuピチューUnlimited

Poké-PowerBaby Evolution

Once during your turn (before your attack), you may put Pikachu from your hand onto Pichu (this counts as evolving Pichu) and remove all damage counters from Pichu.

Search your deck for a Lightning Pokémon (excluding Pokémon-ex), show it to your opponent, and put it into your hand. Shuffle your deck afterward.
