Poorcery version of Avatar of Air, the main theme of the deck is "Throw big minions in their face".
The idea is to have heavy value focused early game with some ramp and card draw as we setup our minons for the fight. Avatar of Air brings a whole lot of movement options for our minions, a Pudge Butcher can be thrown right at our enemies face out of nowhere and just the threat of this attack dwindles our opponents options.
