I also believe that Rider-White's cards are the best and most complete, after comparing them with a huge number of other decks and versions (I think I compared about 90). In my opinion, they are the only ones that give a complete representation of the Universe and, consequently, of the Tree of Life.I recently picked up a "Rider Waite Playing Card Deck" that I'm in love with. The cards are standard playing card size, so I can actually shuffle them properly. Feels so much better than typical oversized tarot cards, and the art is still perfectly legible.
Have you seen this deck called the 'Ukiyo Tarot' Its a lovely Japanese design.....As virtually everyone has stated, the Rider-Waite Tarot Deck is the most universal.
Once you are able to expand your readings and expand your reach, you can find something with a more personal taste.
I found a deck based on the Hanafuda cards but designed as Tarot, so it was unique and I almost bought it. I have yet to find it, even online now.
