The only thing mono aether has a problem with is gravity shield, that and if you aren't being smart about phase shield. 5 Matches is not enough to get a feel for how to play cards in a mono aether, make sure you have 5 pillars before playing a shield, at 70 health start chaining shields and playing dragons. This deck was also originally meant for level 5, not 3, fire would be faster for level 3.
