All Tarot decks have 78 cards with the same characters, energies and symbols in every deck. To read Tarot, one must first learn and understand the meaning of each.
Intuition and Oracle decks on the other hand, do not require any study, prior to use because artists and authors are free to use their spiritual concepts in the cards. Anyone can have a successful reading, from the moment they open the box.
You can use Oracle cards with Tarot to expand your reading (the readings with the combination of the two are more insightful and simply a lot of fun).
