If Girafarig and the Defending Pokémon have the same amount of Energy attached to them, pick any 1 card from your deck and put it into your hand. Shuffle your deck afterward.
Choose 1 of your opponent's Pokémon. This attack does 10 damage for each 1 Energy in that Pokémon's Retreat Cost to that Pokémon (after applying effects to the Retreat Cost). (Don't apply Weakness and Resistance for Benched Pokémon.)
