Having other types of quantum producers would definitely be a good thing, I think. For example more cards in the vein of fireflies, rustlers, soulcatchers, and so on. A weenie entropy creature that produced 1 random quanta/turn, for instance, would be interesting, or a darkness creature that produced(or leeched; but that would probably be OP in conjunction with pests) quanta of your opponent's mark, and so on.
