For an early example of the magic shuffler plot, see Ed Marlo's “Cased-in Shuffle” in Ibidem, Dec. 1956, p. 154 (book edition). Red cards are separated from blacks and deck is put into card case and shaken, which causes reds and blacks to alternate. Method: roughed deck.

Another method is posed by J. K. Hartman in Mr. Gadfly, Sept./Oct. 2001, p. 31. Hartman's “Faromatic” uses a straight deck, with the reds and blacks alternated but angle-jogged, so that the halves of the deck can be riffled to show all red and all black. Deck put into case and shaken. Hartman credits the underlying jog principle to Jerry Andrus (Andrus Deals You In, 1956, p. 170). However, the principle, using straight jogs, goes back to Conradi's “Rouge et Noir” from Der moderne Kartenkünstler, 1896, p. 69; and later in English by Chung Ling Soo in Goldston's Magazine of Magic, July 1915, p. 111, (the description, uncredited and without a byline) and credit note by Goldston a month later, August 1915, p. 133. Robinson and Andrus both used the principle to display the deck as all red cards, then all black, etc. Conradi also published the variant of using end-strippers, replacing jogs, for the purpose, in his “Das Rendez-vous der Farben” from Der Kartenkünstler im XX.Jahrhundert, 1898, p. 204. It apparently took 86 years for someone to see the application to the magical shuffle plot.

Herbert Johnson had a related effect in which the deck is fanned to show the cards in normal orientation; then the fan is closed and the cards dealt to show them alternating face up and face down. White-bordered cards and a narrow fan were the method. This appeared in Walter B. Gibson's “The Instantaneous Reversing Pack” from Twenty New Practical Card Tricks, 1925, p. 16. Another method for the Automatic Shuffler, using a deck of double-faced cards, was created by Tony Chaudhuri. See his Bedazzled!, 1977, p. 42. Still one more early approach was Leslie Guest's magical mixing of reds and blacks in The Linking Ring, October 1928, p. 639. Guest used waxed pairs of cards to disguise their true mixed condition.
