Personally: Pierce, Soft Landing and Falcon... Windmill and Air Temple is great too, but that 3 cards is what the Air needs!
For Air Temple, I think it should be better if burrowed creatures CAN'T hit you while it's in play, instead of being not able to burrow... But that depends on if the WHOLE battle takes place in the temple, or just the user and it's surroundings use it.
Cause if the latter, then burrowed creatures can still burrow but can't hit you cause you way up high. I think that's the same thing with Wings...
