Misdreavus

Poké-Body: Deep Sleep — As long as Misdreavus is your Active Pokémon, each player flips 2 coins for his or her Pokémon that is Asleep between turns. If either coin is tails, that Pokémon is still Asleep. | Return Trance: Return an Energy card attached to Misdreavus to your hand. The Defending Pokémon is now Asleep. | Dream Eater (30): If the Defending Pokémon is not Asleep, this attack does nothing.
