Pop Eyed Popper Deck
Similar in concept to the Svengali Deck, the Pop Eyed Popper Deck is distinct in that you can spread the cards face up between your hands and show them to be different, then turn the deck face down and offer a free selection of what will ultimately (and always) be your force card.
