How do the lava golems work out for you? Seems like they are too expensive for this deck. But you have a lot of quantum pillars so it might work out.
Also with pvp decks I have generally found straight rushes tend to lose to rushes with some creature control added in.
Here's my version of this deck. Other than the graboids, which are fueled by the mark anyway, every single card is 2 quantum or less. So 2 novas=empty hand. With the mulligan and a bit of luck it happens on the first turn often enough.
4sa 4sa 4sa 4sa 4vh 4vh 4vj 4vj 4vj 4vj 4vj 4vj 52o 52q 55u 55u 590 590 590 590 5c1 5c1 5f6 5i5 5i7 5i7 5on 5on 61q 61q
PS - This is the deck I used against you in the last tournament (minus the chrysaora).
