Thanks for the feedback I appreciate it. I'm concepting and working on a more complete version of this game and will keep that in mind. Though the units do come back after death. Behind the scenes, when you play a unit card it moves from your hand list to an onboard list, then when that unit dies the card moves to the discard list. Which just gets shuffled back into your hand. Though because there isn't a way to view your hand or discards that's hard to know. Unless you completely stopped drawing unit cards at some point, which may be a bug.
