Mamoswine GLマンムーGL［ジムリーダー］

Poké-BodyIcy Aura

As long as Mamoswine GL is your Active Pokémon, put 1 damage counter on each Active Pokémon (excluding Water Pokémon) (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 Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.)
