I don't want to be the biggest deck critic around but I saw this and I realized one thing quite instantly:
SoFre
and Sky Blitz seems a lot of overkill. As do 40 cards for an air blitz. I'd personally kill the 6 sky blitz, shockwave and 2-3 wings. One single Dragon also feels slightly... random.
Wings vs Fog Shield is also a matter of discussion. I guess you're keeping it because of flavor, but I prefer Fog Shield due to the cheap cost.
As an example, here's the unupped air blitz I ran (and yes I know it's shardless, I have 4 of every other shard but not a single SoFre):

of course it's slower than any other SoFre blitz but I like this version, especially because of the flying OE providing the much needed/wanted CC. (Shockwave acts the same in your deck though, if you need it to.)
