STS has unlockable cards, characters, and relics by earning XP on each character. This is easy to forget if you’ve been playing a long time because you probably unlocked all of that stuff within the first 10-20 hours of play.
Additionally, you could consider the progression of ascension levels up to A20 as a form of metaprogression. Also the whale bonus changes depending on how well your last run went.
