Heck, why would Blackwing even play Xyz in the first place?
There's no Xyz (at least not right now) that's good for them, and getting 2 Level 7 on the field to summon this card isn't that easy for them. They'll have to use their Synchros, and it's a waste of excellent Synchros to use them as material for this card.
