-The spectator makes a selection, and that selection vanishes without the magician ever going near the cards. The deck is litterally in the spectator's hand during the selection process and the vanish.
-The selection appears among the aces without any extra moves or sandwich loads. Most versions of this effect have a suspicious moment where the aces touch the top of the deck. In this effect the aces are issolated the entire time and the selection ends up reversed among the aces.
