Just some thoughts I had about deckbuilding.
Upkeep:
Some creatures have an ability that are optimal when activated every turn. As a general rule, if your deck is based around these abilities, you should have at least as many quanta generators as the maximum upkeep in the deck.
For example, if you have 6 Chrysaoras, you should have at least 6 Bone Pillars in your deck (Or Equivalent).
Pillars Vs. Pendulums:
While in general using pendulums is more stable than pillars, there are a few exceptions. Sometimes you have a creature that is good to get out on the first turn that costs 2 quanta. A good example is the Devourer. In that case, a pillar split gives you a chance of getting one out early rather than the delay that pendulums give. In these scenarios it you may choose to use a pillar split.
Instant Quanta Generation:
As a general rule, if you rely on instant quanta, then you should not have more creatures than is possible to play with the quanta you produce.
Immolation/Cremation:
The main attacker in an Immo Deck should be playable with one Immolation. Off element cards (If any) should be few and cost no more than 1-2 quanta.
Nova:
General Rule applies. With 6 novas, you shouldn't expect to see more than 2 early. For this reason, unless you have alternate sources, nothing powered by novas should cost more than 2 Quanta.
Super Nova:
See Nova, except with 4 quanta. Also, since you must generate
to use Supernova, you should make your mark
or use pendulums to supply it.
Just some thoughts, let me know if you have any more I could add.
