Personally speaking, I think it really depends on the Major category that you run. While "Beat the Demon" is fairly straightforward, the other two categories (100% Cardopedia and All packs unlocked) are really dependent on which version gets played due the changes in mechanics. I think at least a Pre-version and post-version sub-cat would suffice for now until the game faces a significant update. Then from there, the Stacklands mods can separate each sub category. This is just my suggestion, but I am open to other ideas.
