This should be moved to the deck help section whenever a mod gets to it...
So that's a pretty crazy deck, reminds me of this one I built for random fun, I called it Lots-o-Cards...
And the reason for that is you need a good reason to go above 30 or 40 cards, most 40 card decks at least have additional draw power or stall power or both, even the periodic 60 card decks were usually aether because of the stall power of it's shield in unupped games.
So that's the first thing we need to focus your deck...
Next, you have lots of colors going on, as a Rainbow deck, and Rainbow is fine for mind gates, but remember your mind gates require lots of aether and so do eternities require lots of time... The result is your trying to counter everything with the rest of the cards because of the obvious problems but now it's huge and inefficent...
So, Let's focus this
So first let's focus on the mind gates and eternities
Let's say 4 of each to start
4x Gates
4x Eternities
Both require lots of quanta... So let's make it an Aether make, with time pendulums as your 'core quanta'. You only need to suppliment the rainbow not power the rainbow since you will be stealing their quanta with your cards anyways.
So, 10 pendulums
6 novas
The novas will work well with providing you stall power along with the eternities and draw power when combined with sundials.
So, 6 sundials
That's the core 30 cards... with a speed draw... but no creatures incase it's a creatureless deck you are facing... and no defense against deflags and no way to defend some other things... So... optional from the core, add up to 6 more cards since you will have up to 6 more draw power, let's keep them cheap to be powered by the novas...
1x Deflag (Get rid of something stupid)
1x Flying Weapon (Two eternities really stops enemies, and better control of what's top stack)
1x Ray of Light (For infinite deck)
1x Purify (Reduce poison)
1x fog shield (Reduce damage better than mirror shield)
1x bond (to heal)
Now the decks look like this:
