A card is selected from a regular deck (say the 8♠). A large prediction envelope is displayed and four giant cards (11" × 7") are removed in a stack. The face card is the A♥. The spectator is asked if he selected the A♥. When he answers no, the cards are fanned as you say, "How about the A♠, A♦, A♣?", showing all four aces in a fan.
 
The fan is closed as you say, "But the suit of one of these aces does match your card, right?" When the fan is closed and reopened, one of the aces has suddenly turned face down. It is seen to be the A♠.
 
The spectator agrees that his card was a spade. "Now for the first time, name your card." When the spectator calls out the 8♠, you pretend that you heard the A♠.
"The A♠? I thought you said that you did not pick an ace... Oh! The 8♠." The fan is turned over to show that the A♠ has changed into the selected 8♠.
 
All four cards can be shown on both sides at the end.
 
Can be performed up close or on stage. No bad angles. No extra cards. No sleight of hand. Packs flat and plays big. Ideal for emcees. A quick, visual, direct, and entertaining routine. Very easy.
