Scrolled to find this comment and was not disappointed.

I got a Sabacc deck someplace a few years back. I think it might have been from a storefront in Disney(land|World). But, it looks like you can also buy a set online from a few places.

My son was really into it for a while, but they included betting “credits” with the game that weren’t nearly as fun as normal chips would have been.

I'll add that to my list of fictional card games!

I took inspiration from Yu-Gi-Oh, Card Captors, Angelic Layer...
