I was initially drawn to this deck by the stunning use of color in the artwork, which is crisp and clean. As I took my first look at the deck, I could tell it was one which would be easy to read intuitively, without the LWB or the companion book, also by Ellen Cannon Reed, as the imagery on each and every card is quite evocative.
This is not a RWS clone, and in my opinion, not a deck for a beginning reader. Those who have used RWS style decks extensively will find this deck quite different, as it combines tarot imagery with pagan and Qabalistic symbolism. Most of the Minor Arcana cards (along with a few of the Majors) are interpreted very differently from RWS style decks. I do not think one would need to be a master of the Qabala to read with the deck, although some basic knowledge of the Tree of Life would add to the reader's full use of the deck.
As with many pagan styled decks, the element of air is associated with Wands and fire is associated with Swords. The Devil has been replaced by The Horned One (the masculine force of deity) and The Seeker has taken the place of The Hermit.
The biggest challenge for me personally, and the only drawback to the deck I have identified in three weeks' worth of use is interpretation of the Courts. Court cards in this deck have no interpretation which stands on its own - instead, they are used to modify the card immediately after the Court card. For me, that means laying a spread face up - something which I do not like to do. I prefer to lay a spread with all cards face down, and turn them over one at a time, forming an initial impression of the spread as a whole, then going back to interpret each card in sequence. Still, this is certainly not a fatal flaw, and in time, I'm sure the Witches Tarot will number among my favorites of my modest collection.
