I mean at it’s most basic, tarot is essentially just a random number generator for creating a story.

Ordinary playing cards can and historically have been used for ‘divination’ like this, so there’s no reason Uno cards couldn’t, you just have to assign a narrative element to each card.

If I wasn’t in so much pain right now (endo), this would be a really fun to dive into. I might jot this down actually, it could be my October project.
