Yes I know that, it's why I'm asking how you think I should limit it? Perhaps something with a usage limit on it. I liked the idea of the destroy after turn.
However what do you think of the idea of only quantum of the element a basic or advanced pillar you control can be used in it?
Or even have it say only quantum of the type of your mark can be used and it will generate other quantum. This way you wouldn't get the same kind of quantum you put in. Because the generation of the quantum is random it wouldn't allow you to do it infinite.
