There are many decks out there. How do you know which one is for you?
Most readers, after being at it a while, will collect many decks. That first deck is very important. I suggest beginning with the Rider-Waite traditional deck. The reason for this is the pictures displayed on the card are very connected with its overall meaning. It makes learning easier.
Is this the deck for you? I only suggest this deck for learning.
Once you have an understanding of the tarot, it is time to find that special deck. The connection will be with the pictures of the cards. No one can tell you which is right for you, but I can tell you that you will know. You may even purchase a few decks before you find that one that speaks to you.
There are different types of cards out there. You will find the traditional Rider-Waite theme fairly easily. These are my favorite. But you will also find cards of different themes. Not all follow the meanings of the Rider-Waite. Which is fine, if that's the direction you wish to go, just be prepared for more learning.
Have you found your deck? What is your favorite deck?
