As long as Absol is the only Pokémon you have in play, your opponent's Basic Pokémon can't attack.

Search your deck for a Pokémon-ex, show it to your opponent, and put it into your hand. Shuffle your deck afterward.

Choose 1 of your opponent's Pokémon. This attack does 20 damage to that Pokémon. This attack's damage isn't affected by Weakness, Resistance, Poké-Powers, Poké-Bodies, or any other effects on that Pokémon.
