Step 1: Set The Deck
1) Remove two sets of two cards from the deck. The color of all the cards must be the same. Each set must contain the same number or suit, depending on how you've grouped them. Black seems to work better, and I prefer using the 5 and 9. If you do the same, you will need to remove the 5 of clubs, the 5 of spades, the 9 of clubs, and the 9 of spades.
2) Place one of the cards on the bottom of the deck. In this example, I placed the 9 of clubs on the bottom.
3) Set the card opposite number AND suit at the top. Place the final two cards atop it.
