Thanks for playing and I am glad you enjoyed our take on the theme :)
There is actually a way to save cards for the next turn. There is a card called "Avarice" that makes it so that you don't discard cards at the end of turns. But we noticed that it is pretty inconsistent on what cards people get offered in their playthroughs, so a lot of players unfortunately end runs without seeing 3-4 cards even once sadly. Looking forward, we are thinking of a more "controlled randomness" type solution to make sure people get to see and play every card in their run
