The reason I was attracted to this deck was because it was round. I adore circular tarot sets, particularly the sadly now out of print Tarot of the Cloisters.
That said, I also read the Medicine Wheel, and I enjoy greatly the set that I use, but it is not round. You see, with round decks, you have 360' of dignified and ill-dignified cards. This round deck understands that, like everything of which I can think in Nature, we ease into and out of our situations. Therefore the round cards enable us to ascertain whether we are just entering into this situation, whether we are finally leaving it, or whether we are on our heads smack in the middle of it.
The quality of the cards is good, too. They will withstand a lot of use, although it may take time to get used to handling their roundness. The images are pencil drawings, and while I have to admit the artist is not the most talented I have seen, she doesn't need to be. The images get their meanings across very well, with just over half the card being dedicated to the image and the rest of the card displaying the cards title. Where appropriate, astrological correlations have been included, and there is also room for the reader to make notes onto the cards too, which may be of great value when learning to use them.
The artist has blended traditions from different tribes and nations into this deck, and it flows very well for the most part. The suits are Butterflies, Thunderbirds, Turtles, and Frogs. This resonate with Sun Bears teachings of the Elemental Clans; Butterflies are air, or swords; Thunderbirds are fire, or wands; Turtles are earth, or pentacles; and Frogs represent water, or cups. (To learn more about these clans, try readings The Medicine Wheel by Sun Bear and Wabun Wind.) I found the correlations very easy to understand and use. The card the Hierophant is shown as a white buffalo in this set. Anyone who has studied the story of the White Buffalo Calf Woman as well as the Tarot should be able to grasp the similarity and thus the reasoning for this quite easily. More images and reviews on this deck can be found at [...].
The book that comes with the set is very detailed, and as the set deviates a bit from the usual 'Rider-Waite' tarot images is very useful. For someone reasonably proficient with the tarot they should be able to grasp using this set fairly easily, although I don't recommend it for absolute novices. A background in or passion for Native American traditions is also going to be an asset when using this set.
This set became one of my favorite as soon as I opened it and started to examine the cards, and I have since purchased several more sets as gifts.
