It would work with just the novas and some Basilisk Blood upped, yes. Go Novas, BB, Gravity Force, pillars, Parallel Universe.
Of course, being slower to set up would be disastrous in many matchups for this deck.
I think it is the game which suggesting us to go multi-color, e.g. I dunno how to run an effective voodoo deck with only 2 colors~
If by effective, you mean able to take on Fake Gods with a decent win ratio, then yeah, that's not feasible. Outside of that, Rage Potions work splendidly with these guys, and so do Parasites (need
, but only as Mark, so that's a mono).
