Shiftry ex

After your opponent's Pokémon uses a Poké-Power, put 2 damage counters on that Pokémon.

Target Attack

Choose 1 of your opponent's Pokémon. This attack does 30 damage to that Pokémon. If that Pokémon already has any damage counters on it, this attack does 50 damage instead. (Don't apply Weakness and Resistance for Benched Pokémon.)

When Pokémon-ex has been Knocked Out, your opponent takes 2 Prize cards.
