So, since the theory's base is that 1 pillar produces 5 quanta per game on average, the ratio would be 1:5, and then we compare the base ratio to our current total quanta consumption via a proportion, right? So it'd 1:5 to X:*insert quanta consumption here*. (This part is verification for me, doesn't have anything to do with the next thing)
So the main problem it doesn't take into account that stalls take longer to gain the quanta needed in the deck. But, to counteract this, pillars produce even more quanta on average in a stall. So why not boost the pillar:quanta production ratio from 1:5, to say, 8-9(Number is up for debate). This makes it so the lower amount of pillars is reimbursed with longer quanta generation, because it's silly to assume that the pillars are gonna stop producing quanta in 5 turns. Depending on how long your stall is, the longer those pillars are going to produce. For example, Aether is notorious for having a high QI due to their imbalance in the beginning of a game. But since it's a stall, it will, hopefully, have Dimensional Shields to start stalling with. It only needs 6 quanta to start, and usually those Aether pillars produce enough quanta to finish with Dragons/TUs/etc. mid to late game. It's because those pillars produce more than 5 quanta in a game on average! As I said, a good baseline for stalls is really depending on how the stall works. For example, if it is pretty fast for a stall, the QI base should be barely increased, while a stall that drags out (I'm looking at you, Phase Shield/Lance FG deck) would have a much higher base.
As for auxiliary quanta production cards, here's my opinion on each:
Immolation/Cremation: Since they're mainly used in rushes, I'll assume that the QI base is 5. Since they produce 7/9 respectively, they should equivocate to 1.4/1.8 for fire, meaning that's how many pillars they are equal too. So a deck with six of them would be the equivalent to 8.4/10.8 pillars, which makes sense, since 8.4/10.8 * 6 equals 42/64.8 fire quanta, which is enough for a rush. And to the nova side effect, 0.2 to each separate QI. So let's say we have 6 Immos and 4 novas, we'd have an equivalent of 2 pillars (10 nova-like cards *0.2), which sounds right considering Immo rushes aren't heavy in the other quanta pools. So an important lesson here is 1 quanta is equivalent to a fifth of a pillar. I came with this equation simply by reducing the above ratio 5:1 to 1:0.2 .
Nova: read above midway for detailed explanation. 0.2 to each Quanta pool's QI base, basicly.
Super Nova: read above, except double the amount to give to each pool(0.4 for the lazy people).
Creature Generators: As 10 men said, treat them like pillars, and subtract their costs from their total quanta production (For example, Brimstone Eater would be a 4 since 5(The current QI base, can be changed) - 1(cost) = 4) and then find the correct ratio for the new found total quanta production (In Brimstone's case, he would be the equivalent of 0.8 pillars (5:1 to 4:0.8) In the case of devourer, if you plan to use his Burrow ability, subtract his primary darkness cost from his total production (In this case, 3 is the result), then treat the one time earth cost as a 1 cost card when configuring your Earth QI.
For recurring costs like upkeeps or growth: Treat the cost as -(x/y) where X is the recurring cost and Y is the QI base you have (In most cases, 5). So for example, Lava Destroyer's recurring cost is 1 earth quanta. So you divide 1 by 5 and arrive at 0.2 and then make it negative. So after you count up your Earth Pool Pillar amount, you subtract 0.2 from it.
I guess that's it... correct/ask for clarification/comment/whatever on this if you have any trouble grasping this, as my method of explaining things is usually underpar.
If you didn't understand terms I used in the explanations, here they are:
QI base: The baseline amount of turns your pillars are going to produce quanta. It's what you multiply your number of pillars by and divide by your total amount of quanta consumption (In most cases, 5). I refer to it as a variable because of the first point I try to get through, was that it can change depending on your deck type. Should've used a more clear term than that, lol.
Total Quanta Production: QI Base * Pillar amount. How much total your pillars will produce on average in a game.
Total Quanta Consumption: Total of all your card costs in your deck. This is used to be divided by the Total Quanta Production to see how close the total is to 1.
So yeah, I figure there's a few flaws in this, so please, go ahead and point them out.
