Once during your turn (before your attack), you may put Snorlax from your hand onto Munchlax (this counts as evolving Munchlax) and remove all damage counters from Munchlax.

Discard 2 cards from your hand. (If you can't discard 2 cards, this attack does nothing.) Flip 2 coins. This attack does 30 damage times the number of heads.
