My favourite is the Faeries Oracle. I was as obsessed with that deck (wanting it), as I was with my DruidCraft, four years ago... I still love them both.
I bought the Hidden Path, on Monday, but have only shuffled it a couple of times, so far. The cards are lovely, though. I was drawn to the box, because of the cat on the front ~ he resembles my sixteen-year-old cat, Dennis.
I've barely used my Druid Animal Oracle, but love it. I really need to dig in, and make my own notes about the animals and other things in the cards, so that I can try a spread without having to reach for the book. The few readings I've tried, have "clicked" with me, several days after I've chosen the cards, not right away.
The Druid Plant Oracle was a lovely surprise. I had it on my Amazon wishlist, but wasn't sure that I'd like it. When I received it for my birthday, last month, I managed to get a good reading from it right away (the reading actually made me cry), and I love it. I still have to reach for the book, but as with the DAO, I'll dig in at some point, and study it properly.
