Maybe by removing the phase shields and putting two permafrost shields and Water Pendulums in, this deck would become faster. (Since Fractal and Phase Shields tend to fight over that little aether quanta you have in your deck right now)
And in a lot cases against AI4, Phase Shields tend to get destroyed or stolen, therefore only consuming card spaces which can be used better.
If you want to stay with the Phase Shields, i would consider removing one Abyss Crawler, one Phase Shield and one Fractal to add more Aether Towers for Quanta speed and balance.
That aside, why would I use an fully upgraded Deck, which costs about 45000 Electrum (and is slow), against the small fry AI3? -> a Deck of that cost should be used for Silver/Gold Arena. But therefor, it may be too weak since it doesn´t use much CC/no PC. That´s only a personal opinion of mine...
