Celebi

Once during your turn (before your attack), if Celebi is your Active Pokémon, you may attach a Grass Energy card from your hand to 1 of your Pokémon. This power can't be used if Celebi is affected by a Special Condition.

During your opponent's next turn, prevent all damage done to Celebi by attacks from your opponent's Stage 1 or Stage 2 Pokémon.
