Drapion

Once during your turn (before your attack), you may flip a coin. If heads, choose 1 of the Defending Pokémon. That Pokémon is now Poisoned. Put 3 damage counters instead of 1 on that Pokémon between turns. This power can't be used if Drapion is affected by a Special Condition.

Does 40 damage to 1 of your opponent's Benched Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.) The Defending Pokémon can't retreat during your opponent's next turn.
