Thats what you mean. I agree that pillars would stabilize the deck but in trainer i usually have too much desth quanta in the end. (Around 70, 80)
Having too much quarta by the end of the game is inevitable in decks like these. If you don't want so many quarta left over, you can simply stop using cats' abilities -.-
Would recommend: -6 SoR, +3 entropy towers, +3 bone wall
