This idea has some positive and negative aspects, but since many people believe Rainbow decks are overpowered and want ways to encourage Monos/Duos, what if there were a quanta cap for your entire quanta supply?
For example there would be a quanta allocation screen where you can allocate quanta between the 12 Elements. Let's say, 300 (might be too high).
A Mono deck would probably allocate all 300 to their element, while a Duo might split it 150/150, or 100/200, etc. depending on how important a large quanta supply of each is. A rainbow could allocate evenly with 25 Quanta each but would probably prefer to make sure their more in-demand elements are higher for things like Fractal or spike damage against Miracle.
The idea would need a lot of reworking and the main issue I can see here is that it doesn't hinder stall/bolt decks, which is what the quanta cap seems to be aimed at. I think one important thing to note here is that you would still produce quanta of all 12 types with Supernova or Quantum pillars, so you can't use Quantum pillars with only
allocated and expect to just receive
.
Edit: Just had a thought. If a mono allocated 300 to their element and 0 to the others, Discord would be so much more powerful against them as all of the quanta distributed to other types would disappear and not be usable for the next scramble. That would warrant having at least 10 in each element if you expect Discord.
Edit Edit: Just noticed this is in design theory, so I apologize if I should have posted this elsewhere. Seems like this should have been about a card effect influencing the quanta cap, not a quanta cap idea itself.
