Could most tarot readers who don't do readings purely by intuition read each card and know what it is?
Yes I think so. If you look carefully, the suit symbol and number is fairly well represented. The swords suit might have proved the hardest, and here you will helpfully find small motifs of the Marseille swords blended into the scene, to make it clearer
The courts might be the most difficult to tell apart without their titles, but that can be true of other decks as well.
Yes it's a deck with a strong atmosphere, but it's definately a tarot deck with atmosphere, rather than an oracle.
Just as an aside, I think that all the images are avaliable to view on the new website.
