TCG Rulings

 * If you have multiple copies of this card in your hand, you can activate all of their effects in a Chain.
 * If your “Blackwing” monster is destroyed by battle and sent to the Graveyard, you can still use this card’s effect.
 * If you control your opponent’s monster at the end of the Damage Step, you cannot activate this card’s effect because that monster is no longer “that opponent’s monster”.
