Blastoise ex

Poke-POWER: Energy Rain

As often as you like during your turn (before your attack), you may attach a Water Energy card from your hand to 1 of your Pokémon. Put 1 damage counter on that Pokémon. This power can't be used if Blastoise ex is affected by a Special Condition.

Flip a coin until you get tails. For each heads, your opponent discards an Energy card attached to the Defending Pokémon.
