You can see the appearance of airburn unit here. This unit is a strange looking unit that looks like a genie. You can see it holding a plate thingy, and a fire burning on the plate. It's ability maybe is fire magic. If the ability is really fire magic, it can call the God of Fireballs to destroy it's enemies.And it is a unit that players never seen it before, only the lucky players will have a chance to see it. Maybe it appears in Stick War 3 the new game.
Nothing confirmed... but it is confirmed that
AIR + FIRE = AIRBURN
