This has worked really well in Gauntlet (near 100% win rate) as well as most fights in the campaigns. I run it in casual once in a while and win more than half.
I tried to stick with the flying theme with the exception of switching to Jennev Merchant rather than Winchest Merchant because the Primal marketplace worked better for me. You can check the sideboard if you want to switch them around and see some good Justice options for the marketplace.
You can also switch Hooru Pacifier out of the marketplace if you feel you won't use him since he will interfere with your weapons, but I found him to be useful in the case of an emergency when you are up against a Fire deck that produces a lot of weapons.
