I understand your confusion. There are probably thousands of decks, each unique with its own apeal. I prefer classical ones and have started a collection of decks published before 1900. These are reproductions, mind you, I couldn't afford originals. But, because of their antiquity I feel a stronger tie to the original thought behind them. Those decksa are 1) Soprafine 1850's or there abouts, and 2) Etruria cerca 1725. Only 2000 decks were reproduced for each of these decks, and so they hold a special place for me because of that. You might be able to go online and find one for sale, though I would never let mine go.
In the end, the deck you choose must speak to you. Without that voice being heard before you buy it, you will have a hard time hearing anything after you do.
There are 2 decks that I recommend to anyone wondering which deck to choose and learn on.
One is the Morgan-Greer Tarot by US Games. The other is the Robin Wood Tarot deck published
by Llewellyn Worldwide. They both have clear large images that are easy to read and interpret.
They both have a definite Pagan feel to them. I based my minimalist method of reading Tarot on
these 2 decks. Once you get your deck, go through them and familiarize yourself with the cards.
One tradition is to sleep with the deck under your pillow for at least a week to attune the deck to you.
Record your dreams while you are doing this. Use a natural fabric such as cotton, linen or silk
(the tradition is black silk) for a reading cloth. I have quite a few Tarot books, but unless you are
really into books, no book is really necessary, unless you want to wait for The Ultimate Guide to
the Tarot, which Stephen Abbott and I are in the process of writing now. That book will be a must
for anyone who wants to know the Tarot. Draw one card each day, and see how many events in
your day remind you of this card. A lot of people like to say that learning to read with the Tarot
is a difficult process. These people just like to pump up their own importance. It is as complex
and difficult as you believe it to be. What it really is about is trusting your own native intuition.
Everyone has it. It's how our ancestors survived to become our ancestors. Develop your
intuition, and you will find that the effort gives back in so many ways.
I am new to Tarot as well. I really didn't decide I wanted to learn the cards, they sort of chose me. I just felt I needed them. I looked at several card / book combo's and chose one that was fairly simple and straight forward. I guess what I didn't understand is that while the book's explanation of a meaning is only a guide and I at once understood that more was being told to me.
I have gravitated to the Mythical Tarot which just felt "right". That is the best advice I can give. When you see the one that is "right" for you, you will know it. Listen and the cards will chose you.
I have been taking a course through "Magickaschool.com" on the Tarot, it is free and extremely enlightening on all aspects of the cards from their origins to the influence of the Golden Dawn, Eliphas Levi, A.E. Waite, Israel Regarde, and Aliestar Crowley on the cards.
For instance, the cards originally came from Fez in Egypt in the 14th century to Italy and then France, they were called "Mamluk" cards then. They have been used for gaming, meditation, and divination a very long time.
The Psychologist Garl Gustave Jung was fascinated on the effects the cards have on the human psyche and the impact they have on archtypes. C.G Jung was most famous for rather cruel experiments that give tangible evidence that we have souls.
The Ancient Hebrew mysticism of the Kabbalah is embedded in most of the cards we use today.
There are 2 decks you should at least consider one of. They are the Morgan-Greer Tarot published by US Games (Stuart Kaplan) and The Robin Wood Tarot published by Llewellyn. They are both Pagan inspired and have large easy to read images.
