Hey, it's not bad! I'd rate it an 8/10. Let's see if I can make any fixes..
MONSTERS:
-1 Sirocco the Dawn (2 is enough)
SPELLS:
-1 Pot of Duality (You already have enough draw power, plus you need that special summoning)
TRAPS:
-1 Trap Stun (One really is enough, when you think about it)
-1 Royal Oppression (Could hamper you as well, you should probably just stick to siding it.)
Not alot of cards to add, though I have suggestions just in case.
Blackwing Shura (Great card, especially in the start when your opponent sets a monster, grab another Blackwing)
+1 Blizzard (A key card in Blackwings, should be run in 3 in my opinion)
+1 Delta Crow Anti-Reverse (Great for clearing backrow)
+1 Breeze the Zephyr(Works really well with cards like Raptor Wing Strike, and it's good for BW Synchr (That's all it does
)
That's all I can think of for now o-o
