***TRIALS RESPONSE***--------------------------------------------------------------------------------
This is quite an original way to build a mono aether deck. I understand you're desire to stay away from Dimension shields since it's what 99% of mono aether decks do. Can mono-aether still be a threat without those.. sure it can!
I still got some issue about you're deck though. You wanna fractal spiders and maybe sparks on last turn which is allright, but it means almost all of you're deck is vulnerable to creature control. The deck can live with that since it will play so many creatures (unless a mass creature control card comes in like Rain of fire or thorn carapace). But since you wanna do that, why add immortals and phase dragons? These cards cost more and all you're opponent will do is target you're other creatures. If what is intended is to play the immortals/dragons first and then start to fractal, you are only slowing you're deck.
I would suggest to add some pendulums, switch a couple of pillars to pendulums also ( to prevent earthquacke ruining the deck), add a fractal because with only 2, there is great chance 1 is in the bottom deck part and add a lobotomizer to prevent growers without spending a lightning.
Here is what it could look like:
