That seems very complicated. I started thinking about it and then gave up, though I’m sure someone like @Szaal could come up with something.
I think your best bet would be to find another Choicescript game that includes a card game, open up the code, and learn from that.
I did find this thread that has some thoughts on the subject: Dumb questions from noobs like me
Alternatively, do you have to make the card game actually playable? You could absolutely write a scene that fakes it without going to the trouble of simulating the deck.
Even from your example, it seems like your intent is more the “hanging out with friends” angle than taking the player through an accurate rendition of Go Fish. You could still include actions like drawing cards, calling Go Fish, etc, and just prescript the outcomes, or predicate them on other stat checks.
