Gengar & Mimikyu-GX

Card text

Poltergeist: Your opponent reveals their hand. This attack does 50 damage for each Trainer card you find there. Horror House-GX: 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.)
