If this card is face-up on the field, you cannot use it for a Synchro Summon. If this card is in your Graveyard, you can remove from play this card plus 1 non-Tuner Blackwing monster in your Graveyard, and Special Summon 1 Blackwing Synchro Monster from your Extra Deck whose Level equals the total Levels of the removed monsters. The effect(s) of that Synchro Monster is negated.
