Poker Transformation

The magician holds three cards fanned in his hand, and three are on the table. He picks up the first card from the table, and adds it to his fan showing how all the cards have a blank face. He swaps the card that he has just picked up with another one from the table, and suddenly all four cards in his hand are now four aces! But that’s not all because swapping one of the aces with the last card on the table,  incredibly the four cards in his hand now change to four kings!

In a rapid succession of effects, the cards held by the magician transform nearly visibly.
