What if the cost for creatures was no longer paid quanta? A 10 merely means you have to have 10 death pillars minimum. That means, with 3 life pillars, you can play as many frogs as you have frogs, but anything more than 3 . How would the game have to be rebalanced?
The first thing to note is that 2 creatures cost less than twice the cost of 1 creature. (Except in the case of 0 cost creatures where it is exactly equal)
1 11 cost creature would have an equal cost to 11 1 cost creatures or 8 4 cost creatures or 6 6 cost creatures.
5 11 cost creatures would have an equal cost to 15 1 cost creatures or 12 4 cost creatures or 8 8 cost creatures.
Each card would individually have a benefit equivalent to a 0 cost creature. Playing a pillar would enable access to the next tier of creatures. Access to the next tier of creatures would have a net benefit equivalent to the net benefit of a 0 cost creature. The value of a 0 cost creature would need to be large enough that these net benefits could be expressed via incremental stat increases.
Nightfall gives all
and
creatures +1|+1 for 3
+ 1 card.
A semi vanilla 4|2 (Phase Spider) costs 3
+ 1 card.
Photon would be buffed to 4|2 stats, each +1 cost would translate into +1|+1 stats.
Card advantage in all forms (including activated abilities like snipe or growth) would be severely nerfed.
Mitigating effects would be strengthened. Removal and Negation would be nerfed.
Some effects like quanta denial would be removed.
