Hippowdon LV.X#107 · Rising Rivals

Once during a game on your turn (before your attack), each player shuffles all cards in play (excluding Pokémon and Supporter cards) into his or her deck. You can't use more than 1 Sand Reset Poké-Power each game.

Discard 2 Fighting Energy attached to Hippowdon and choose 2 of your opponent's Benched Pokémon. This attack does 40 damage to each of them. (Don't apply Weakness and Resistance for Benched Pokémon.)
