An effect by Nick Trost
. One of the most incredible routines with two (regular) decks of cards. A spectator selects four cards from a red-backed deck, without looking at their faces. These four cards are inserted into the middle of the blue-backed deck. Now you remove four blue cards, show them to be indifferent and insert them into the red deck. The spectator’s four red-backed cards are turned over, and they are all Kings. Your four blue-backed cards are turned over to show they have changed into the four Kings! A double climax! Two regular decks are used (not supplied) and you end clean with two complete decks that can be used for other routines.
