I am with jema, I also love this deck. A few years ago it was one of my main decks. I must say I have not used it recently though but I think I should get it out of its box again.
The artwork is odd, some cards look like expressionistic paintings, these are the cards I prefer, and then some cards have a lot of straight lines like they have been made with a ruler, the Devil comes to mind.
I must be odd, because I actually find a lot of the cards appealing
but maybe that is because it is a true Tarot of the Spirit for me, there is so much expression and feeling in the cards. And maybe I am just bored with pretty decks that are easy to read with but don't add anything.
I would recommend the book as well, it made it easier to read the cards and I found it thought provoking.
