there's nothing wrong with your deck. The only thing is that it's not so creative and it certainly can be improved. you put a life mark, could have put some pendulums too.
1. Avoid PC
2. gives sufficient quanta for firefly
3. fire fly produces 
. why choose that instead of other creatures since you don't want to use the quantas?
or putting rustler? heal? or even epinephrine?
4. Wyrm should be ok. Running upped version, you'll see me using 5 wyrms and 5 fireflies, you can add 3 or 4 blessings. Mark: 
fog shield, weapon, and pillars + pendulums for the rest of cards till 30
Yeah a duo with
quanta especially with crusader and animate weapon then maybe wirms and blessing with a sky blitz to overkill the ennemy going to try that out and say my ration on 10 AI3 later
-2 FFQ.
-1 OE's
-2 Animate Weapon.
+2 - 3 wind pillars
+2 - 3 Sky Dragons
Pack the punch.
Not a real fan of wasting my weapon since it's not that easy to get 3 of the same type.
Actually, this is a mono deck (only air cards).
Secondly:
-2 FFQ.
-1 OE's
-2 Animate Weapon.
+2 - 3 wind pillars
+2 - 3 Sky Dragons
Yeah but I wanted to make it a duo.
