The Knockout Deck is based on the Sneak a Peek Deck. I would be interested to know who invented the Sneak a Peek Deck and what the difference is between these two trick decks. Someone wrote here in the Magic Cafe: "It does have a slight difference... very slight...". Thanks in advance.

Basic effect Knockout Deck: The magician shows that all the cards have a blue back and are well shuffled. He riffles through the deck at one corner, a spectator says stop and remembers his chosen card. Effect 1: Suddenly, the spectator's card moves under the joker at the bottom of the deck. Effect 2: Suddenly all the cards have turned into the spectator's card. Effect 3: Suddenly all the backs are red.
