Cassandra Jean has created Shadowhunter Tarot Cards. Some of the cards have been switched out for others (you can view all the unofficial ones here), but Cassandra Clare announced on her tumblr that the card deck has been finalized. There are around 70 cards in total. Some of the cards we have seen before and some we haven't, but be ware, there are spoilers! To see all the official cards so far, click here.
We’ve moved on from the Major Arcana to the minor Arcana — the first suit is the suit of Rings, which takes the place of the suit of Pentacles. The Five of Rings is the Blackthorn ring. It shows the Blackthorn family, TDA-era, in all their glory. Tiberius looking crabby as usual, Julian messing around, Mark being serious.
The Five of Pentacles (Rings here) can often represent going forward after suffering a loss.
