Although there are different schools of tarot and variations from deck to deck, “any tarot deck you pick up will have the Major Arcana covering what we call ‘The Fool’s Journey’. In other words, major archetypes or lessons we encounter in life and the Minor Arcana, which covers the more day-to-day experiences,” AMJ says. “Oracle decks typically don’t follow that setup. You may find a deck with 30-something cards or 80-something cards,” they add. “One oracle deck might sort of mirror the tarot, while another could have absolutely nothing to do with tarot. But overall, the big difference is in the number of cards and whether it’s split between majors and minors.”
