Whenever your opponent's Active Pokémon retreats, your opponent flips a coin. If tails, this power does 20 damage to that Pokémon. (Don't apply Weakness and Resistance.) This power stops working while Dark Dugtrio is affected by a Special Condition.

Your opponent flips a coin. If tails, this attack does 20 damage plus 20 more damage; if heads, this attack does 20 damage.
