I have a few favourite Oracles, namely:
Graven Images Oracle: My No 1 love the images I have always had a thing for cemetary statues & they really speak to me..
Symbolon : Beautiful Colours with gold & they feel like silk, for me this is an intuitive deck and works well
Tea Leaf Fortune Cards: Lovely cute circular cards that really give great readings, people seem to love them
Madame Endora : A real no nonsense straight talking deck of cards, they give the answers to lifes pressing questions shooting straight from the hip! & I love the art too.
Playing Card Oracles: A good system, nicely illustrated cards very enjoyable to use & give good insight.
Tarot D'Eltynne: not a tarot at all lovely colours and I love using them
Faeries Oracle : haven't used much recently but they remain a firm favourite, their cheeky energy shines thru in their readings
