There may be one or two guys out there interested in this little thing. I want to get a few opinions on it and also find out whether it's already in the literature before I claim it. The illusion is that a packet of cards,when snaped, turn instantly into different cards. Four indifferent selections into the four aces for sake of argument. The use of the Marlo style snapchange is used to create the initial change of a face card and the cards behind are Already aces.
The switch of the indifferents can be made early using the vernon addition leaving one indifferent card at the face in view. The other seletions are left on the deck and the aces come out secretly in place of them, it is then only a matter of executing the snapchange letting the face card ride around the back and out of sight exposing the aces which are already there. A lovely natural touch is that the cards fan out slightly after this, which is perfect as the other aces can then be seen without any other movement of the fingers. What do you think?
