This is by Caitlín and John Matthews. Has anyone used it before ? It gives a celtic spin on the tarot deck. I am new to Tarot and the design of this deck really appealed to me. The book has something called a Hallowquest which goes through meditations of each card in the Arthurian word. Any thoughts ? Also, the suit is the sword , spear (wand) , grail (cups) and stone (pentacles).
