Naii made a QI tool:
https://etg.dek.im/forum/index.php?topic=1061In original the idea was to go for ~5 QI & go from there. Bit higher for rushes, bit lower for stalls
12 pillars was people just riffing off MTG, being able to play all pillars asap makes it better to run way more quanta. But player's having so much health somewhat tempers that
I tend to calculate how copies I need per card based around getting the desired quanta/cards played in first few turns. For stalls that's how fast you can shutdown opponent's first few turns
