The Ultimate TTRPG Tarot is based on the classic Rider-Waite Tarot deck, and doesn't do much to alter the overall style of the deck. Instead, Zachary Bacus and colorist Hank Jones replaced the classical esoteric imagery with things straight out of a D&D game. For instance High Priestess has become a Mindflayer, albeit a nerdy one with glasses and a DMG. The art also reflects the overall humor of the cards, which is stuffed to the gills with references and in-jokes straight out of a TTRPG convention. It's sort of like if you mixed a tarot deck up with a game of Munchkin. That writing comes from Jef Aldrich and Jon Taylor, hosts of the System Mastery podcast, who bring their pretty wide experience in tabletop to bear in this deck.
