Flip a coin. If heads, the Defending Pokémon is now Paralyzed and discard an Energy card attached to the Defending Pokémon.
You may do 60 damage plus 40 more damage and 40 damage to 1 of your opponent's Benched Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.) If you do, Mamoswine does 40 damage to itself.
