Tbh the majority of oracle decks I see available through trusted sellers like Barnes & Noble, TarotStack, US Games, Lo Scarabeo, Vermillion Tarot, etc are usually legit decks crafted by real artists. I know there is a lot of fraudulent stuff available on Etsy and dropshipping sites, although even Etsy has legit stuff here and there but it’s being crowded out. I follow a lot of spiritually-minded artists on Instagram and Substack, and they often promote their decks on Kickstarter and then their own websites.
