Munchlax DP 33

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.
