Well, so far my favourite is the Faeries' Oracle. Those faeries are such good freinds of mine.
Also adore my Tao Oracle..it's so beautiful. And it does more than give you answers. It tells you what is currently changing, advice for the change and what the final outcome will be (if you follow the advice). You do it with three coins as well as the cards, so it's fun!
I have a very good feeling too that my Healing with the Angels Oracle will become a fast favourite. It is still in the mail making it's way to me. But I had a reading already done for me with it that was beautifully life changing. I know it will become one of my favourites very quickly.

PS, I have the Dreaming in Color deck too. It is stunning. A really beautiful deck. I like it a lot but it did not make it into my list of my top decks just because it gives me rather short answers. It talks to me, doesn't for me have the depth of some of my other decks.
