Thanks so much! The encouragement has been really helpful. Those are great suggestions for unlocks, and I'm definitely going to implement those in the future.
Also thinking about different starting decks to unlock as well.
A couple of set of starting deck to unlock is a good one as well. Your game doesn't really have main character so I wouldn't want to focus too much on that
Curious to see what starting deck you plan to brainstorm and whether or not you want starter deck to be new cards or existing cards (I prefer latter and having few starting deck option would increase more things to unlock, such as "win this run using this starting deck")
