There are several such effects like this, accomplished by the use of an
extra card, or a double faced or double backed one. Others make use
of the one handed pass as the deck is given spectator behind his back.
Mulholland, Farrelli, and McAthy each describe a method using this
pass. (See Editrivia. Ed.) I never could do the one-handed pass well
enough to make use of it.
Another disadvantage of that pass is if the spectator accidentally (?) brings
deck to front he sees that the top card is face up.
In my method a deck is shuffled and held face up for a spectator to select
a locator card, at the same time you noting the face card and second card
from back of deck. The locator card is removed and placed face down
on face up pack. Then you predict the noted cards, and let someone
hold the prophecy. You then place the deck behind the spectator’s back
turning it over as you do. He takes the top card (supposedly turned over
card), pushes it somewhere in the deck, gives the deck a cut, and brings
it to front. You run through for the reversed card and the two prophecied
pasteboards are disclosed. In my method, if the spectator should bring
the deck forward he sees only the turned down top card. This way makes
it more applicable to circumstances where people are on most sides, one
thing not possible with the other ways.
