Hehe.. playing Aether will be a fun challenge at the start. It could use some Phase Spiders for variety, perhaps? As a side note, I personally find Earth's deck to contain the best card mix. Earthquakes, 6 Dragons and Stone Skins.. yes please. Especially since the latter was buffed.
In the end though, mixing in other elements in deck-building will be pivotal for many at the start, and to that end we'll find more uses out of the given cards. On the whole, I agree with Xinef's comments on Aether, but I'm sure the decks will be much more balanced when this shindig kicks off. :>
