Mimicry

Choose an attack on 1 of your opponent’s Pokémon in play. Mimicry copies that attack. This attack  does nothing if Mew  doesn’t have the Energy necessary to use that attack. (You must still do  anything else required for that attack.) Mew  performs that attack.

Rainbow Wave

Choose 1 basic Energy card attached to Mew . This attack does 20 damage to each of your opponent’s Pokémon that is the  same type as the basic Energy card that you chose. (Don’t apply Weakness and Resistance for Benched  Pokémon.)

You can’t have more than 1 Pokémon in your deck.
