The Black and Silver edition features shiny silver foil on all of the court cards, the Ace of Spades, one of the two jokers and of course, the back design. All four aces have large custom center pips in the theme of the floral back design. Gilded edges! A gilt card is a beautiful card. But it's well known that gilding interferes with how cards feel and the smoothness of fanning. With the help of Cartamundi, we are working with gild specialists in France whose work not only protects the quality of the cards, but enhances the pack's magical features, and defends against humidity and hand moisture that so often weakens un-gilt cards along their vulnerable edges. The marked edition contains 54 cards, a double-backer, and an instructional card which explains the marking systems. All Butterfly Playing Cards Black decks are printed by Cartamundi on Slimline card stock with the True Linen B9 finish. What is the difference between the marked and unmarked cards? The marked Butterfly deck will empower you to perform miracles not possible with any other deck of cards in the world. So if this is your goal, go for marked.
