A straightforward packet poker routine.  Showing four clubs and a spade, the magi explains that a crooked gambler might try to claim this is a flush in a fast, loose game.  But it is only a "Four Flush" so don't fall for this gamblers ruse.  But even worse is the cheater who can switch in winning cards at will -- the four flush almost instantly changes into four aces.  (It is a super clean change!)   But the magician does a secret magic move, and the cards are now his own winning hand -- a royal flush in spades.  

The cards are seen front and back at the end, so the finish has a very clean look and feel.  No cards are removed or added throughout the routine.  Typical good gaffed card thinking from David Solomon.
