The key to any deck is to ask the following: what is my win condition, and how do I get to it quickly? If your proposed win condition is "fractal deja vu" then focus on how you can do that. You'll draw fractal and deja vu more often if you have more copies of them; you'll get fractal and deja vu more often if they make up a greater percentage of your deck-- if your deck is smaller. And you'll be able to play them sooner if you have the quanta to play them when you draw them. Consistency is key!
There are two major points to hit on:
1. Identify and focus your deck around a win condition. Optimize how you get to it, both by increasing the number of copies of key cards(the stuff that is vitally important to your strategy), and by reducing unnecessary cards that you'd draw instead of those key cards.
2. Balance the amount of quanta you use vs what you can generate. If you have too much quanta usage, reduce the number of expensive cards that take up a lot. If you have too much quanta production, you can then consider fitting in some utility or bonus cards that would fit if you replaced a pillar or two.
