Wigglytuff

Once during your turn (before you attack), if Wigglytuff is on your bench, you may flip a coin. If heads, each player removes up to 2 damage counters from his or her Active Pokémon. This power can't be used if you have already used another Wigglytuff's Good Neighbor Poké-Power this turn.

Flip a coin. If heads, this attack does 10 damage times the number of Pokémon you have in play.
