here’s a pdf version of the thing i made into a generator a while back, an expansion of the Deck of Many things from D&D 5e made to fill out a tarot deck of 78 cards. it’s intended to be a part of the ARDENTS module, but it works on its own just fine. there’s an npc in there too if you feel like keeping her.
if you need a tarot deck to use at the table … or just need a cool tarot deck … i recommend the Marigold Tarot by Amrit Brar. it’s the inspiration for the one described.
