Mawile/100 - Reverse Holofoil Sandstorm - Holo Rare

Look at your opponent's hand. You may have your opponent shuffle a Supporter card you find there into his or her deck. If you do, your opponent draws a card.

Before doing damage, you may switch 1 of your opponent's Benched Pokémon with 1 of the Defending Pokémon. If you do, this attack does 20 damage to the new Defending Pokémon.
