I don't like this card because with a Water mark and a few light pillars you can generate 12 quantum every turn, with 11 pools of quantum open for stuff like Dragons/Spirits/Golem/etc. Nova is quick, but it can only generate at most 22 quantum upgraded (the upped sacrifices a bit of speed in the early turns of the game as well). Multiple copies of these on the field could easily make up for the quantum you lost in a few turns along with a lot more quantum in your other pools for high-cost spells and creatures.
Perhaps make it usuable only twice?
Also, welcome to CI&A! 
Possibly, I could give it another ability that makes it lose hp per turn or every time it uses it's skill? For example, Rainbow would make it lose 1 HP every time it's used, that way it would not be infinite. Then I could lower the HP of the upgraded version to 4 or 5 HPs so it couldn't be used too much. And also being susceptible to CC your Sun's wouldn't be too overpowered.
Thanks for the welcome

Yeah, water was the point of the "rainbow" lol, and that way it balances because it's much more difficult to use than the Nova (which costs nothing). Also, I was thinking that using a quintessence and Sun deck would be too much of a hassle to be effective. I mean, instead of filling your deck with Sun's and quints you could have better creatures.
rainbows actually usaully have a couple quints like Sg's has one but people modify it to have 3. Many rainbows don't have a barrage of creatures. To make an effective rainbow you need CC PC monsters pillars defense. CC can be an oty Pc deflags or steals pillars are quantam or nova or suns defense is shields like bonewall. For monster you may want to quint a firefly queen(i do that), A fallen elf to mutate fireflies or skeletons from a boneyard. though its not needed.
it would be super effective with quint on it because nothing can take it down besides flooding.
i mean if you made a rainbow and replaced a couple quantum pillars (4) with two suns and 2 quints you'll prob not need as many pillars
I mentioned above that I could make it lose HP every time it activates it's skill, so even quintted it would die out. This would make it more balanced, I think, so having immortal suns wouldn't give you an unlimited supply.
