Switching the mark to gravity and adding an even amount of pillars makes it more likely for you to gain all three elements. Further, Momentums are more important to draw, that's why I would play it with either 4/4 or with 5 momentum and 3 photons for the draw chance. Further, I would add either the time shield or darkness shield to get some more defense.
1) Precognition can help because you know what he will play next turn. (Does he have CC in hand? Does he have a Dim Shield? any other nasty cards?) So if you know the opponents hand, you can play your deck a bit smarter, which can save a game sometimes. And by the way, Precogs don't create "card disadvantage" or use "deck space", but only cost some quanta.
2) Novas are kind of stupid in this deck, because you would need to draw at least 2 or 3 of them (2 if you have time mark and remove most of the dark cards, or 3 with darkness mark) to make this deck running.
