The Pokémon this card is attached to can use the attack on this card. (You still need the necessary Energy to use this attack.) If this card is attached to 1 of your Pokémon, discard it at the end of your turn.
Choose up to 2 of your Benched Pokémon. For each of those Pokémon, search your deck for a card that evolves from that Pokémon and put it onto that Pokémon to evolve it. Then, shuffle your deck.
