That is amazing!!! To this day I still love browsing wikis and BoardGameGeek images for card games I've never played and in all likelihood never will, just to love the cards themselves and the idea of extracting a character or phenomenon into some sort of mechanized bundle of rules and numbers.
I'm definitely interested in exploring what you've done with what Catalyst provides/implies! 👀 You could also submit to #NotAGameJam2020, where Natalie first submitted Catalyst. You might find interest in another Catalyst "expansion," "The Forgotten Village" by Colton Flick.
