Interesting deck.
You can lose the Purify; not many rainbow decks use Poison as a source of damage. Otherwise, it looks pretty good. What worries me is your usage of Quantum Towers to fuel cards from only 6 elements. Are you good in terms of quanta? Do you ever find yourself running thin?
Solution #1: Lose the Quantum Towers and turn this deck duo or trio, with Fire and Aether, I guess.
Solution #2: Lose some cards from elements you are heavy on and bring in cards from other elements that are useful.
The second solution is probably better. For example, you can drop 2 Phoenixes for 2 Giant Frogs for Fractaling; you can drop 2 Phase Shields for 2 Protect Artifacts. Things like this would help smooth this deck out and make it faster.
Another issue: Where are the Black Holes? These are the ultimate anti-Rainbow cards. Get some of these things in here!
Otherwise, great deck.
