Designed by a High Priestess of Irish Wicca, this vibrant deck is based on many ancient Irish traditions. The cardstock is a little thinner than average, but the deck fit nicely into my hands and shuffled easily fresh out of the box. The 83 cards are visually striking, mostly well drawn in vivid colors. The backs, featuring all four suit symbols and a triple spiral, seem very "busy" and even a little distracting. The companion book is inconsistent in style, sometimes fascinating, but often getting bogged down in the Celtic (Gaelic?) terminology. The book leads you through a first-person spiritual journey through each elemental suit of the Minor Arcana - Aer (Air/Swords), Tine (Fire/Wands), Uisce (Water/Cups), and Domhan (Earth/Pentacles). The Helper (court) cards have been renamed as well, becoming the Ridire (Prince/Knight), Ard Ri (King), Annir (Princess/Page), and Banrion (Queen). Each Helper is an Irish folk hero, but their stories are often hard to follow and don't really seem to fit their rank and suit. Alongside the basic 78 cards are the four artifact cards, elemental talismans to help you on your journey. The Major Arcana also start off with an extra card, the Crann na beatha (Tree of Life, numbered 00). The deck includes associations for nearly everything, from compass directions and seasons to times of day and even trees. Plenty of spreads are also included, focusing more on meditation than divination.
Once I got used to the correspondences to "standard" decks, this was a decent deck to work with. I would not recommend it for beginners, but it makes a nice addition for the tarot enthusiast who wants to expand on their foundations.
