Mine is the Witch's Oracle. I adore it! I love the cards and the books. I use it for everything. Each card has an incantation in the book, too, and I love those also.
Vessel Oracle. When I'm itching for an oracle I'm usually looking for some straightforward guidance, and I find the Vessel's emotion-based cards to be exactly what I need.
It depends on what I'm doing.
If my clients request a reading, I offer a Rackham Oracle Celtic Cross. If my clients seem to require increased support with closure, I go to Earth Magic.
If I'm reading for myself I'll go with either Earthbound or Goddess Guidance, depending on what I'm looking for.
I have three oracle decks I keep returning to: The Fairy Ring, The Enchanted Map, and The Heart of Faerie Oracle.
I like The Enchanted Map for self discovery, and The Heart of Fairy Oracle for relationship questions. The Fairy Ring I like for about all other queries.
i love the artwork of them all (yes, I'm a Celtic Romantic) and they all have excellent books that came with them.
