Comments: Third in a series, the other two being Master Poker Demonstration and Royal Triumph. In this effect, one by one, the four Aces are placed face up between two face up Tens. With a simple snap of the packet, the face-up card turns face down. For a surprise climax, the four face-down Aces change to four Kings.
