If you have any Supporter cards in play, this attack's base damage is 20 instead of 70.

You may discard a Claw Fossil, Mysterious Fossil, Root Fossil, or Holon Fossil from your hand. If you do, choose 1 of your opponent's Benched Pokémon and do 30 damage to that Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.)
