Gardevoir δ

Poké-PowerEnergy Jump

Once during your turn (before your attack), you may move an Energy card attached to 1 of your Pokémon to another of your Pokémon. This power can't be used if Gardevoir is affected by a Special Condition.

Choose 1 of your opponent's Pokémon. This attack does 10 damage for each damage counter on Gardevoir to that Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.)

Does 10 damage plus 20 more damage times the number of your opponent's Benched Pokémon.
