Today I added a Joker to my cartomancy deck.
I decided to draw an Angel to represent the spiritual part of the Joker, the Holy Fool who travels the lifepath.
My way of cartomancy with the Blue (Neutral) Joker:
Whenever I would use the whole deck in a 8×7 spread, I first shuffle the Joker in the deck to become the significator in the spread.
After laying down the cards in the spread, there wil be one card left as a special comment on the spread.
To add another layer of interpretation I might choose to draw one of my malachim cards to receive a message from the Angel of the moment.
