Time Triumph by Juan Pablo

Imagine having a normal deck of cards and super clearly mixing half of the cards face up and the other half face down and now you leave them in the hands of the spectator to square the deck and leave it on the table. Now you ask the spectator to take out their cell phone and look at the time because you, in less than an instant, are going to arrange all the cards in a super magical way.

Now you snap your fingers on the deck of cards and spread all the cards on the table and the entire deck of cards will magically appear face down except for 4 cards that when shown coincide exactly with the time the spectator is on the cell phone at that moment. Time Triumph is a super modern magic effect.
