The max amount of a card is 18 in case you don't know, because you only have 12 of each card as max. I think the growth deck should take some squids for renewable creature control. 3 squids perhaps? And the entropy/duo can take a discord or two, early discord is painful death to most duos. And I object your suggestion to take quantum pillar for the entropy deck, novas are more consistent. Perhaps 4 novas?
