If you can get hold of it somewhere, I think the Pamela Colman Smith Commeorative Set could be a pretty cool place to start. It usually retails at around £30, but for that, you get a beautiful Rider-Waite deck, TWO guidebooks - 1 which gives insight behind the artwork and another which instructs on how to use the cards, as well as 4 postcards and a Tarot bag!
Essentially, all you'll need to immerse yourself in the world's most popular Tarot deck!
I found that learning about the artist helped me to understand the deck a lot more, and having the Tarot Bag and Postcards was just a cool extra.
Worth a look
