Hey, it's pretty... unorthodox I'd say. I can see that you are going mostly for lvl 8 synchros, I can give you a few suggestion that come to my head, but you'd better give me some more explanations on how do you want this to work.
+ 1 Black whirlwind - this card is too good to be played at 2, max it
- 2 Blackback / + 2 Call of the haunted - CotH is much better
- 2 Against the wind / + 2 Dark Eruption - does pretty much the same thing, you won't be able to add high attack blackwings, but at least u wont hurt urself.
- 2 Dust Tornado / + 2 Mystical Space Typhoon. MST is better because it's a spell and you can play it immediately.
- Battle Tuned / 2 United we stand - those are good cards, but do you really need them? Blackwings are fairly strong by themselves. There are just better cards to play instead, like
+ Compulsory evacuation decice
or
+ Torrential Tribute
or
+ Book of moon
or
+ Bottomless trap hole
Choose 2 from those 4 and you should be good.
