As long as Mamoswine is your Active PokÃ©mon, put 1 damage counter on each Active PokÃ©mon (excluding Water PokÃ©mon) (both yours and your opponent's) between turns.
Flip a coin. If heads, this attack does 10 damage to each of your opponent's Benched PokÃ©mon. (Don't apply Weakness and Resistance for Benched PokÃ©mon.)
