True, that's what I was trying to imply when I said it's necessary to progress. I suppose someone could maybe devise a mod to provide evidence to the contrary, but I'm pretty sure the starter deck pool simply wouldn't have enough scaling to survive at higher ascension levels.

That said, I would absolutely love some kind of mechanic that allows you to control the contents of the overall pool to some limited degree as well. (Too much freedom would essentially trivialize the game and I'm not sure if there's any mechanic that would provide effective counterplay to a literally stacked deck)
