I'd like to point out a few things:
- Immo/Crema is a spell that cost -7/-9
and -1 of every other Element. Similarly, Nova costs -1 of every Element.
- A creature that you have in your opening draw that produces quanta every turn is a pillar. The pillar costs the casting cost of that creature plus the number of turns it take to play him in quanta that creature generates.
- A card with an ability that you will use every turn can be treated as a creature that generates -X quanta every turn where X is the cost of that ability.
(All the statements above are true without the context of QI)
- You can calculate QI also by drawing your whole deck and counting the turns it takes to play everything.
- QI isn't a super-useful concept imo.
