I collect Tarot decks in a casual way, mostly because I like the pictures. Haven't read Pollack's book, so can't help there. Always thought Tarot was a nice way of giving one's hands something to do while one mustered one's thoughts and discovered what was already known about any question being asked.
Didn't know there was such a thing, but guess I'm not surprised. I'll look forward to hearing about your Tarot adventures if you ever care to share them.
