Well as u can see from my profile pic i love blackwings haha.
So what are you going for here? are you trying to make it actualy competative? if u are you might want to try the Vayu speed synchro engine. and dont focus so much on Xyzs, the deck isnt very capable with that. with my deck irl i only run 2 Xyzs. utopia and Utopia ray because of shura with bora. Basicaly all the advice im going to give is take out situational stuff.
so with the monsters
-1 mystic tomato. not needed. if the deck is consistant enough u wont need it.
-1 battle fader. its ok to take some damage. and he is a dead draw most of the time
-1 blackwing breeze guy at the top next to DaD.
-1 Blackwing - Armor Master
+1 Blackwing lv 8 synchro
-2 Blackwing - ghibli, the searing wind (very situational)
+2 or 3 Dark Grepher
+2 more Sirocco the Dawn
(the vayu, grepher and sirocco things are for if u decide to use a vayu speed engine which i advise.)
+1 Kalut the moon shadow
+1 Zephyros the elite
for traps and spells i only advise using traps that effect the opponent's field. Blackwings are very offencive and you cant focus on saving yourself or there will be alot of dead draws.
Traps i use are Compulsary evac, solemn warning, delta crow - anti reverse (very helpful), and icarus attack. 2 of each of those. then i use 1 starlight road.
thats all i can say for all that. oh and focus on draw power with spells. like pot of avarice, black whirlwind, allure of darkness, etc.
I think my Essay on Blackwing efficiancy is long enough haha. Hope this helps if u want it to be competative.
