I've attempted this kind of deck many times. I'm certain phase salvs do not have airborne.
I also found brave chaos balls or brave blessing balls can out rush mono air but they are about tied, but not out rush chaos wyrms, the bravery feeds them to out pace you anyways. Instead I found fractal balls and brave fractal balls to be able to out rush those or control them, to prevent their rush and setup a bigger hit a turn or two behind.
I re-present 100 OTK Pillarless Fractal Balls
and
The Brave Big Ball That Could
In the 100 OTK fractal balls you may switch out the purifies with other cards, for customization, I use a purify, sanctuary, and 2x shard of divinities myself
In the Brave Big Ball that could you can swap the shield with another more desirable shield. The Brave Big Ball that could also has a 40% WR against FGs with an 8 TTW average making it around the equivalent FGei of Poison Dials, but no where the Malignant Balls or Brave Voodoo, so you can swap out for a while if your bored with one of the others for FG grind but I wouldn't make it a primary FG grinder.
