replace a class after defeating the final boss?

keep custom cards in later runs, limited number of uses? do you replace a card in your starting deck with a custom card? maybe starter decks have 1 legendary, 2 epics, 3 rares, 4 commons or whatever which can be replaced with the same rarity

how far you can go leaderboard = the daily challenge, same seed / starting point, your score on the leaderboard is how far you got

earn points based on your performance in the run. points can be redeemed for something, including cash prizes or something that interacts with a constructed collection marketplace.
