The magician places a prediction in full view prior to the start of this effect, and points it out without revealing its contents.
The spectator is handed a rather unusual set of cards. Each of these has various suits and values printed upon each side. The spectator thoroughly mixes the cards before dealing them into pairs, creating a series of random playing cards.
The spectator very fairly eliminates each of the pairs until only one remains. Both the suit and value are shown to match the magician's prediction - the very one that was in full view from the outset!
