Rider Waite Tarot

Both types of decks are used for insight, perspective, clarity, personal growth, inspiration, coaching and divination.
Historically the Tarot has ancient roots while Oracle Decks (angels, fairies, guides, fractal etc.) are the new kids on the block.
However, they are structured quite differently. The tarot follows it’s own set of rules laid out by original masters of days gone by, while the artists of oracle cards are free to do whatever they want.

Here’s the comparison:

Tarot

The tarot structure is predictable. If you learn the Rider Waite, then you will most likely be able to read any other tarot deck.
Tarot always has 78 cards (except Osho Zen – he added himself)
Major Arcana = 22 cards relating to major events and life pivoting events
Minor Arcana = 56 cards Page, Knight, Queen, and King

Oracle Cards

Oracle decks are structured independently and each follows it’s own set of rules
They may have any number of cards usually between 36 and 64.
Rarely have suits, although they are often numbered for guidebook reference.
Some have a bit of a tarot theme while others do not.
Some have the meaning of the card printed on them.
Novices refer to guidebooks for information and in many cases; it is acceptable for professional readers as well.

Is one better than the other?

No – they are different. It’s the deck you love that will work the best for you.

Oracle cards tend to be easier to learn, while tarot takes a level of practice and mastery to become proficient and offers an expanse of information at a depth that most oracle cards can’t reach.
Many professional readers add an oracle spread to their tarot sessions to pick up or amplify messages received.
