To set up this trick you reverse one of the decks. So one deck is hearts, spades diamonds, and clubs and the other deck is club, diamonds, spades and hearts with king to ace.To start the trick you have a friend shuffle the two decks together. You then make a bet that the top 52 cards will make a full deck. Ace through king in each suit. You count out the top 52 cards. Then organize them into suits to show that there is now a full deck.
