Rainbow unupped [PvP, half-blood] upping decisions ?

[AchDeToni]

Hey,

so i'm pretty new to this game, but still like it a lot. That's why i need some help with my rainbow deck.
Made some other decks before, but this was my best build so far:

4sa 4sa 4sa 4sa 4sa 4sa 4sa 4sa 4sa 4vd 4vj 4vj 4vj 4vj 4vj 4vj 52q 55u 55u 55v 590 590 5c1 5c1 5f6 5fa 5fb 5i5 5i5 5lm 5lm 5og 5rl 5rl 5rl 5up 5up 623 7q5 8ps

Using it for PvP1 (changing the upgraded hourglas for an unupped) and half-bloods farming. Winrates are about 55-60% for half-blood and 80+% in PvP.

Arsenic will be replaced by either Eternity or the entropy weapon (forgot the name), if i get one.

Tried to cover all elements with my cards so no quanta stays unused, besides that I like the control engine in it.
So, do you have some improvements for it ? Maybe speeding it up ? Usually i lose against very fast rushes, especially with a medium/bad hand. Another Problem is a shortness of fire quanta sometimes (gravitons using it to grow).

Furthermore i don't know how to specialize it further for PvP / farming, what are good improvements to perform better in each of them ? Finally i need some help with which cards i should upgrade first.

Thx for any help in advance =)

btw: if you find some typos or grammar errors, be kind i'm not a native speaker

Un-upped I would recommend
-quantum pillars instead of novas
-RoF over a single rage pot
-1 shield is going to be unreliable

Something like this might be better
