Pichu

Poke-POWER — Baby 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.

Energy Retrieval: Search your discard pile for up to 2 basic Energy cards and attach them to 1 of your Pokémon. Put 1 damage counter on that Pokémon for each Energy card attached in this way.
