This is where terminology might start getting us confused… I’ve seen companies using “angel cards” as a way to sell Bible quotes on bits of paper but since we’re comparing to the Tarot I’m going to assume that this is the kind of thing you mean (please feel free to correct me).
If this is the case, then really it doesn’t matter which deck you’re asking about because all you need to know is the difference in Oracle and Tarot decks.
Honestly… if you don’t have a reason to choose between one or the other then my advice is there is no difference and they’ll both perform the same task.
I’m sure others will come in and get more into the nitty-gritty and their experiences (we have a lot of talented and knowledgeable people here), but I don’t think it really matters. If you just want to start doing readings, then an oracle deck like these Angel cards will do the same thing as your standard Tarot deck.
