Each basic Energy card attached to your Pokémon now has the effect "If the Pokémon Energy is attached to attacks, the attack does 10 more damage to the Defending Pokémon (before applying Weakness and Resistance)." You can't use more than 1 Dark Shadow Poké-Body each turn.
The Defending Pokémon is now Asleep. Flip 2 coins instead of 1 between turns. If either of them is tails, the Defending Pokémon is still Asleep. If both of them are tails, the Defending Pokémon is Knocked Out.
Put this card onto your Active Darkrai. Darkrai Lv. X can use any attack, Poké-Power, or Poké-Body from its previous Level.
