Cassandra Jean has created Shadowhunter Tarot Cards. Some of the cards have been switched out for others (you can view all the ones that are out 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!
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 Three of Rings shows Cristina and Jaime Rosales from The Dark Artifices. Cassandra Jean has included Cristina’s pendant and Jaime’s crossbow, and the rose-pattern ring of the Rosales family.
Jamie and Cristina are not brother and sister. Interestingly, the Four of Pentacles is a card that can be about fear of love: losing it, or getting it.
