You can also activate this card from your hand if you control a “Blackwing” Synchro Monster or “Black-Winged Dragon”.
(1) When a monster your opponent controls activates an effect: You can send 1 face-up “Blackwing” monster you control to the GY; negate that activation, and if you do, destroy that card. Then, you can Special Summon 1 “Black-Winged Dragon” from your Extra Deck.
