This is an Aggro Avatar of Air deck for the mobility. It also has fire because of Cavalry and Blaze, which just helps the overall theme. You do need to be careful with your placement of sites, because you can only blow while on an air site. I would mention that while playing another Aggro deck (e.g. Sorcerer, Battlemage, AoE) you want to get one of the 3 Free Cities as a powerful blockader. One piece of key info is that all fire cards need one threshold, so if you get more than one you may want to mulligan. There are 3 deserts in here just for Deathspeaker, but you should keep it if it is your only fire.

Also, this deck got me 6th at Courtesan Cup.
