My favourite one of these is "Troonblinka"
I think they're oracle cards. Here's another angle (caption: "magic is art therapy")

Basically tarot is a bullshit parlor game where you interpret the cards to have certain meanings and so pretend you're being offered guidance about the future or whatever. It's aided by cold reading and guessing what the person wants to hear.
However there's supposed to be a pattern to interpretation (e.g. "sevens represent a need to introspect, and cups represent fulfillment, so as it's in your significator position in this spread and it's inverted, it's showing that at this time the emotional refuge you once sought is not healthy and you're currently feeling fearful and confused, needing to search within for guidance and clarity on how you truly feel"). Therefore it's technically possible to read them wrong ("Oh, seven of cups! Well the cups are made of gold so I think it means you're going to be really rich!"). So you basically need to study them (or google that stuff, but that kinda ruins the I'm A Magical Priestess Seeing The Future bullshit Bonnie is larping at).
Enter oracle cards. Oracle cards are mostly just pretty pictures, sometimes with writing that literally tells you things like "Beware of negative energy, you may be sensitive to emotional vampires". They're not standardised, so Bonnie probably bought a "spirit animal oracle" because Peruvian (no Peruvians didn't have spirit animals). There's no spreads where the cards in different positions are supposed to mean different things, there's no esoteric symbolism you're supposed to have learned to interpret, you just pull out a card with a dolphin that says "remember to smile" and you personally interpret it to mean whatever you want because it's a message to you and only you, so you conclude that this means you should smuggle Kindness to the ranch again. It's tarot for people who want to pretend to be spooky, but are too lazy/exceptional to even manage tarot.
