I only own a few oracle decks; they are:
Goddess (Marashinsky)
Well-Worn Path
Hidden Path
Beasts of Albion
Celtic Tree
...and a DV, I think it's Archangels
The DV was a tag sale find and I haven't done much with it. The Celtic Tree I haven't done anything with in about 15 years. (!) The others I've studied quite a bit, but the only one I've done any actual divination with is the Goddess, and I like it very much! As for the Paths, I got them in reverse order and studied them separately, then Hidden got accidentally sent off to storage, so my grand plan of working with them together has had to be put on hold.
