Lycanroc-GX

When you play this Pokémon from your hand to evolve 1 of your Pokémon during your turn, you may switch 1 of your opponent's Benched Pokémon with their Active Pokémon.

This attack does 50 damage for each of your opponent's Benched Pokémon. (You can't use more than 1 GX attack in a game.)
