I bought the deck soon after our exchange here - only the deck, no book, and I decided to buy the dark deck.
It is a beautiful deck, shuffles like a dream - it's extremely smooth and has a wonderful size. I also love the box it came in.
It took me some time to start reading with it, but the few readings I did went very well. This is a hybrid between playing cards and tarot, which is quite challenging - they read so differently, and here, they're together. But now that I have become more accustomed to this deck, I like the strong difference between majors and minors. It really emphasizes the power of the majors, they really come from another world.
The suit/elementary associations work well for me but still, Pentacles and Diamonds "feel" differently to me so it's strange to see them on the same card. I feel this deck stretches me a bit and that's a good thing.
I don't use it often but when I do, I'm very happy with it.
