Ace problem by Creative Artists (Download)

Four Aces are on the table and a selected card is under spectator's hand. Four face down Aces will twist one by one until there's only one Ace. This time the last Ace and the selected card under spectator's hand have changed positions. Subsequently the 3 remaining Aces transform to a four of a kind like the spectator's selected card.
