Gengar

Psychic 120 HP Promo

Screaming Circle

Put 2 damage counters on your opponent's Active Pokémon for each of your opponent's Benched Pokémon.

Netherworld Gate

Once during your turn, if this Pokémon is in your discard pile, you may put it onto your Bench. If you do, put 3 damage counters on this Pokémon.

On the night of a full moon, if shadows move on their own and laugh, it must be Gengar's doing.
