I bought one for myself a while ago. I think a Rider Waite 78 card deck, because they seem to be the most used original decks.

But i never really put the time in to learn all the meanings and patterns, so i'm not the best reference.

They look nice though.

Edit: i got this one: https://www.amazon.de/gp/aw/d/B071YNQSB1

Like the other comment, Rider Waite is OG, but Albany Waite has cooler colors IMO.

I’d go with either of these original sets and then they can venture into the infinite varieties of decks out there.

Modern Witch Tarot is full of feminist iconography and has beeeeeautiful art.

Get her a pig and name it tarot deck.

I've always wanted a pig.

I'm not into tarot that much (I just like the art usually, doubly so if it's from an IP I'm a fan of), but if she is or ever was into Neopets, the Neopets Tarot Deck on their merch site is only $22 and is pretty nice.

It comes with a guidebook in case you need tips or instructions on how to start, or just need a refresher on things. The art on the cards is fantastically done, with each card representing what it is extremely well with just the picture alone. Plus, each card is packed full of lore and little nods to different NP plots/characters from over the years. The guidebook tells you what each card represents/means, plus a description of the art and how it pertains to the card, and a bit of fun lore/callbacks (like the Game Graveyard being the representative art for the Ten of Swords card, or Tor being the Knight of Pentacles)

Osho Zen is the most beautiful tarot deck (not just visually but the explanations of each card are both clear and give a story! Dont know what it costs in the US.

thanks y'all for replying!!!

I'm gonna get what she'll like the most

There is a lovely Skyrim Tarot deck. A bit outside your range there, but I saw it lower elsewhere.

My favourites are Lost Hollow and Kitten Tarot. Tip: you can get both together for less than 15 bucks on Aliexpress or Temu

There is a wide variety on temu. I was surprised at the quality of them.
