Pichu δピチューδ-デルタ種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 discard pile for an Energy card and attach it to 1 of your Pokémon that has δ on its card.
