This deck is Hard. It's complex and layered. (ha! get it? cuz you layer the cards?) I would absolutely call this an advanced deck. I've been reading for quite a while, and I rely on the book whenever I use them.
Now - the only criticism I've got is that they had an oily film on them when I got em. I wiped them down, and didn't dry them all the way so the next time I got them out they stuck together again. They were a bit of a pain in the ass, but a nice side effect of this was that I had to spend a lot of time getting to know these cards. After you get the funk off of them, they read beautifully. I love the process of layering the cards and seeing what connections are made. The rainbow touches the man who is on his knees -showing hope. Death strides toward the Lovers. They truly paint beautiful pictures.
The creator of these lovely things is Ms. Emily Carding - actor, author, artist and all around Renaissance woman (currently starring in a critically acclaimed one woman show of Richard III). I suspect Ms. Carding is part fairy, and this is why her deck is so ethereal and beautiful. And I'm hardly ever wrong, so there you go.
