-2 SoR, +2 Phase Shields?
Let me elaborate on my post above a little bit. SoR's are quite nice and works well in here, but 6 is quite overkill. Phase Shield, on the other hand, will increase your survivability, so it should be a good change.
This is especially important when using Mono Aether. You have, no creatures, no heals, and limited permanents. This basically means you need a better way of defending yourself from oncoming attacks, and while it may seem cliché to do, Phase Shield spam may be the one thing that wins your duels.
I also found the following scenario amusing:
You use this deck, your opponent uses the original, unupped Mono Aether deck. Who do you think will win?
