This is majorly unbalanced with quanta. ( hard to say that with a rainbow but.... )
Ok this needs some fixing.
You need to meke more quanta, and also the total of those nightfalls are 9, it is very hard for you deck to even make 3. I know you only play 1 but it is hard to play a 3 cost card unless you get lucky with a quantum piller and play like 1-2 novas or you need half of your novas!
It needs more quantum pillers for sure.
Take out 1 lightning, 1 fogshield, 1 nightfall, and 1 deflag ( maybe 2 because shields dont matter after you stack poison or have momentum creatures. )
Then add 3 quantum pillers, and maybe another freeze?
The point of these changes is to make it so that you use 3-4 at most of a certain quanta besides quanta matching your mark, and nightfall. ( because you should only play one per game anyways, but you will have 2 in your deck. )
