First, remove the last card in your deck image. That's your mark card. In addition, in your post, where it says MARK=Something, put LIFE where 'something' is. If you're going for half rainbow half aether/mindgate, you have the beginnings of a good deck in either but not both.
Go either fully with the 'mindgate/qp rainbow' or with the 'duo aether/life' deck setup. Having both, especially without time to speed things up, makes your deck awkward and dependent on luck for a good draw.
Suggestion 1:
-3 lightnings
-Parallel universe
-6 aether pillars
-6 dimmensional shield
Replace them with 6x silence and some, 2-4 precognitions. Silence slows down your opponent while precogs speed up your deck.
The Lightnings are good for cc, but they're not as effective if your main goal is to use the mindgate.
The PU is taking up space. While it can be useful, if it is that important to your strategy you should have more than 1 of it. The Dim shields are great for stalling, but they take too much space if you're going for a rainbow. Besides, if you're using 6 heals, a sanctuary, a vampire dagger, and jade staff, you should have enough healing. As you're using less aether quanta, you won't need as many pillars.

Suggestion 2:
Remove everything not from life or aether.
Remove the mindgates.
Add in 3-4 adrenalines, 4-6 forest scorpions, 3-4 quintessences.
Replace 1/3 or 1/2 your aether pillars for aether pendulums, as you need more life and less aether.
