Ooh, good question. Five of them I own, and five I just desperately want. In order:
1. Medieval Scapini tarot: Some people find this deck dark, but I love the layers of symbolism and the detailed art.
2. Japaridze Tarot: Beautiful, thought-provoking art.
3. The Fantastical Creatures Deck: This deck took its time to grow on me. At first I thought the colour palette was too limited, but when you read with these cards the different shades become clearer. There is a startling range of emotion, as well.
4. Sacred Sites
5. Il Tarocco delle Vetrate: The art is beautiful and clear at once. This is a fantastic everyday deck.
6. Zerner-Faber (Enchanted)
7. 1001 Nights: This is a deck that rewards familiarity. At first glance, the images are busy and the LWB is useless, but when you start getting to know the cards, you understand how they reflect the meanings of the cards.
8. Secret Forest
9. Universal Fantasy
10. World Spirit
