When Pokémon-ex has been Knocked Out, your opponent takes 2 Prize cards.
Once during your turn, when you play Espeon ex from your hand to evolve 1 of your Pokémon, you may choose 1 Evolved Pokémon on your opponent's Bench, remove the highest Stage Evolution card from that Pokémon, and put it back into his or her hand.
Choose 1 of your opponent's Pokémon. This attack does 30 damage to that Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.)
