OVERVIEW
Six pairs of cards are separated and mixed into two stacks. A large card is shown printed with "Cards Will All Be Re-Matched."
An volunteer is selected from the audience. Cards are dealt from each stack, for each letter written on the large card, with the spectator saying when to switch dealing from one packet to the other.
Amazingly, all the cards are rematched with their mates!
Also available in poker-sized cards.
