Sadly, the Buffy the Vampire Slayer Tarot is never to be, but check out the crisp, clean darkness of the recently issued Vampire Tarot by Robert Place. Heavily inflected by the novel Dracula and other literary vampires of the 1800s, the Vampire Tarot has novel Major Arcana [such as Jonathan the Fool {hah!}, Mina, the Count, the Madman {Renfield}, etc.] and Minor Arcana. Its four suits are Garlic Flowers, Stakes, Swords and Holy Waters.
I am gratified to note that several of the cards refer covertly to the polymorphous perversity of literary vampires, with the Queen of Holy Water being the famous lesbian vampire Carmilla and one of the Major Arcana being the hungry, sadistic, omnisexual Brides [of Dracula]. Poe and his reanimated heroine Ligeia also appear, so the deck may more properly shade into Gothic and supernatural, rather than just the vampiric. It is pretty damn awesome, even though there is no Baudelaire card.
