Tengu power!
Although if you can't keep the flow of blackwings monsters or somehow screwed by opponent, then it would be the opponent who broke you. :V
Of course, if you can't keep Blackwings flowing then there's something wrong with you.
Gale: Regular-rare, tuner, halves the ATK/DEF of an enemy of your choosing. Can be Special Summoned if you have another BW.
Bora: If you control another BW can be Special Summoned, has decent ATK and Piercing. Common.
Sirocco: Lv5, 2k ATK, can be Normal Summoned if you have no monsters, can pool the ATK of your BWs into ONE BW (coughBoracough), but no other BW can attack save the one that got pooled into. Common.
Shura: Decent ATK, when it kills something you summon a BW from your Deck. Common.
Kulat: Discard from hand to pump a BW BY 1400 ATK a la HONEST (hence my nickname for it, Honestbird, which came from a discussion topic about it). COMMON.
And then there's the back-breaking support; stuff like that trap that can be played FROM YOUR HAND if you have 3+ Blackwings, the Blackwing version of Graverobber (which has a disproportionate cost), Raptor Wing Strike (return a BW you control to your Deck, add a BW from your Deck to your hand), and Black Whirlwind (if Normal Summon a BW you can add a weaker BW to your hand -- coughSiroccoThenGalecough).
Then there's the Synchros, of which you only really need one (the first one, which cannot be destroyed by battle, and anything it fails to destroy in battle can just be killed with the resulting 'Wedge Counter' [I sh!t you not, that IS its name]).
. . . So yeah, Blackwings are officially the most broken archetype in the game, barring Chaos.
