Traditional tarot is represented by the Waite Ryder Deck. It is the one I recommend for teaching  and learning. All other tarot decks  come after , when you choose a distinct type of deck. There are a lot to explore. A deck has to resonate with you and call to you. An oracle deck has pictures and symbols with descriptions. They come in multiple guides to choose from. I now work with a Fairy Oracle Tarot Deck.  .
