Here's an original spread

Well maybe it is original. I've not seen this before.

It apparently is useful with the Ancient Minchiate Etruria 1725 Tarot.

Has anyone used this spread with this deck?

very interesting spread. i'm gonna take note of this in my journal. it's also very timely that i'm expanding my tarot correspondences (currently applying basics of astrology and numerology) to add basic concepts of kabbalah.

thanks for sharing
