I have over 50 decks (most I just recently inherited) but my favorite is the Mary Hansen Roberts deck. The imagery is wonderful, the clothing is very reminiscent of the Renaissance Faire and the deck size is like a regular set of playing cards, much easier to handle. I suppose lots of people don't like that because they are too much like poker cards, but they also travel well for their smaller size. When your back packing the smaller size wins! Though I don't backpack anymore
I also resonate with the Wildwood Tarot, but haven't really did any readings with them, just love the art on that deck.
But I got to say my most reliable and accurate readings have been with the colorized version of Ryder-Waite, it's my first and most used deck though I would really like to branch out and try some of these mystery decks I received. One is real trippy, called simply the Morgan deck...do wa-ka do, is the fist card. (I think) If you can find that deck it is real different, single card readings lend much pondering.
