This is going to be a very basic review, as the intricacies of the Ordo Templi Orientis are outside of my personal practice. While it has the Rider-Waite as a framework, the esoteric aspects are layered in multiplicity throughout.
The tuckbox version comes with a Little White Book that surprisingly helpful given the lack of volume. Each of the cards helpfully has the name of the card printed upon it, as well as where it fits in the deck as a shadow behind that (ie trumps, cups, disks, wands, swords). This will help the reader when using the deck as a basic tarot deck for sure.
This deck utilizes the Tree of Life, so a knowledge of the kabbalah will help the reader get the most out of readings. An understanding of the Golden Dawn would also be beneficial. As you can see in the cards I’ve highlighted, there is a rich symbolism at work here.
I would not recommend this for a beginner simply because there is so much going on to learn – tarot, kabbalah, esoteric studies. But at the same time, I do not recommend people accept arbitrary limitations – if this deck speaks to you, by all means get a copy.
