The typical tarot deck has 78 cards, but the Shadowhunter deck will have an extra Fool card, totaling 79 cards. The Shadowhunter deck also has new names for every card and suit, basically translating the original Arcana into Shadowhunter lingo: Swords are Blades, Wands are Steles, Cups are Runes, and Pentacles are Rings. Despite this, the card numbers will still correlate with the original tarot card numbers.
