Volcanion ◇ボルケニオン

AbilityJet Geyser

Once during your turn (before your attack), you may discard a Water Energy card from your hand. If you do, your opponent switches their Active Pokémon with 1 of their Benched Pokémon.

This attack does 20 damage to each of your opponent's Benched Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.)
