Reddit mentions of As Above Deck: Book of Shadows Tarot, Volume 1

"Modern" is a pretty broad category -- it would help to know more about what kind of art style you're looking for. For example, are you hoping for something that's more minimalist, or detailed? colorful, or monochrome? digitally drawn, or painted? focused on figures, or more inventive with imagery?

That said, here are some decks in a pretty wide variety of styles that come to mind when I think "modern art." I personally own the first six decks on this list and can vouch that I like them; the rest I don't own but I know other people like them.

• The Light Grey Tarot
  
  
• The Cosmos Tarot & Oracle
  
  
• The Body Language Tarot
  
  
• The Fountain Tarot
  
  
• The Dark Goddess Tarot
  
  
• One of my all-time favorite decks, a feminist classic Thea's Tarot is apparently getting a second printing soon! Maybe not in time for your friend's gift, but perhaps for the future.
  
  
• The Book of Shadows Tarot, Volume 1: As Above and Volume 2: So Below
  
  
• The Wild Unknown Tarot
  
  
• The Wooden Tarot
  
  
• The Prisma Visions Tarot
  
  
• The Linestrider Tarot
  
  
• The Wanderer's Tarot: Solar Edition and Midnight Edition
  
  
• The Golden Thread Tarot
  
  
• The Illuminated Tarot (note that this is a playing-card style deck with 53 cards instead of 78)
  
  
• Dame Darcy's Mermaid Tarot
  
  
• The Prismatic Tarot
  
  
• The Ethereal Visions Illuminated Tarot (I'm including this even though Art Deco is decidedly not modern because it is very different from the traditional RWS style, so your friend might like it anyway)
  
  
• I don't know of any specifically videogame/media themed decks, but The Steampunk Tarot does come to mind as being up that alley, thematically.
  
  I have to stop here otherwise I'll just keep on going, lol, I love talking about different tarot decks. So I'll just leave you with a note that there are lots of items in the Little Red Tarot shop that might interest you.
  
  Hope this helps!
