Putting asside the fact I detest mono aether for various reasons...
as xSIn said, QI is a bit low, but its not as low as it might seem because Phase shield is not to be played as soon as drawn, but rather as a 3 turn chain.
Tbh the deck is as good as it is going to get, the only thing i would say is that this kind of deck is extremely slow, and i would reccomend to a new player to take a more fun, fast deck because it will earn you more early electrum, and probs keep your interests longer.
