Gengar & Mimikyu-Gx (53)

Your opponent reveals their hand. This attack does 50 damage for each Trainer card you find there.

Your opponent can't play any cards from their hand during their next turn. If this Pokémon has at least 1 extra Psychic Energy attached to it (in addition to this attack's cost), each player draws cards until they have 7 cards in their hand. (You can't use more than 1 GX attack in a game.)
