Tarot vs Oracle Decks
Although both types of cards are commonly mistaken for each other there are a few things that make them different.
Number of cards:
Tarot is commonly known to have about 78 cards. Some decks include 1 or two bonus cards but generally most decks stick with the common 22 major arcana, and 56 minor arcana. However with Oracle decks you can have anything amount of cards in a deck, some have as little as 12 cards to as much as 105 cards, and anything in between.
Tarot cards are traditionally the same each deck has about 78 cards, 22 major arcana and 56 minor arcana with 4 elements or cups, wands, swords or pentacles, and then the 4 court cards of the king, queen, knight, and page. This way it’s easier to learn to read tarot since you know what you're going to get with each deck. On the flip side Oracle cards are all different, each deck has a different number of cards with different meaning, much like snowflakes no two Oracle decks are the same, and because of this reading with Oracle Cards you tend to rely on the guide book for the meanings of each card.
To me Tarot is like that bitchy friend that isn’t afraid to tell you that you fucked up, and how you fucked up, but then helps you out of that situation. Meanwhile Oracle Cards will tell you that you fucked up, but in a more gentle approach, maybe sit you down, give you a hot beverage, and then nicely tell you that you fucked up. It's really up to you how you would like to be told that you fucked up, or depending on the day you are having already.
Overall each one may have their differences but they are both excellent tools for divination, and one is definitely not better than the other. Honestly if you work mainly with tarot cards maybe try a week with an Oracle deck,and vice versa with Oracle decks maybe try a week with a tarot deck, or maybe try doing a reading with both decks. The possibilities are endless but definitely give both of them a chance, you won’t regret it.
