Once during your turn (before your attack), if Arceus has any Energy cards attached to it and your Bench isn’t full, you may put 1 Basic Pokémon card from your discard pile onto your Bench. Put damage counters on that Pokémon equal to half its HP (rounded down to the nearest 10). This power can’t be used if Arceus is Asleep, Confused, or Paralyzed.
A Mari Usque Ad Mare
Does 30 damage minus 10 damage for each type of Basic Energy card attached to your Pokémon to each of your opponent’s Benched Pokémon. (Don’t apply Weakness and Resistance for Benched Pokémon.)
