Blissey

Once during your turn (before your attack) choose 1 of your Benched Pokémon and flip a coin. If heads, search your deck for the number of Energy attached to Blissey and then remove that many damage counters from the chosen Benched Pokémon. This power can't be used if Blissey is affected by a Special Condition.

Flip a coin. If tails, this attack does nothing.
