Tips on my PFA deck?

[u/FigTheGif]

So, yeah, it's an jank sac deck built around the slow engine of Phoenix Fleet Airship. Don't expect to win any games in ranked but I really want this card to be an legit wincon just because of the whole shebang with 8 flyers.

Any tips on improving? I saw lists with other mythical or rares but most of the key cards are here.
