My favorite tarot deck is the Tarot of Vampyres by Ian Daniels, because it is Thoth based (despite the box saying that is Rider Waite based), it comes with a great book, has Qabalistic lore in relation to vampyres, illustrations are great and the author wrote delicious personalities for the court cards that actually are like people. It’s a dark deck that has actual depth.
My most beautiful tarot deck is the Marseille Cat Tarot, but I’m unable to read it because of its mixed nature of Merseilles and Rider Waite and zero Thoth references
My most special cards is my Thoth Tarot by Aleister Crowley, I have the large edition. It has been tainted by my relationship with a Scarlet Woman, thus all the meanings are about her, much like Chinese people have expresions about horses because of Mongolians. It has been used so much by me that the grease of my hands has darkened the sides of the cards.
