Choose 2 random cards from your opponent’s hand. Your opponent reveals those cards and shuffles them into their deck.
At the end of your opponent’s next turn, the Defending Pokémon will be Knocked Out. If this Pokémon has at least 1 extra Psychic Energy attached to it (in addition to this attack’s cost), discard all Energy from your opponent’s Active Pokémon. (You can’t use more than 1 GX attack in a game.)
