Pichu

The electric pouches on its cheeks are still small. They cannot store much electricity yet.

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.

Electric Circuit: Search your discard pile for up to 4 Lightning Energy cards, show them to your opponent, and put them into your hand.
