I find the best way to do this, is to have all the cards separated by card. Then have a spectator
choose and card, and you can guess it. Spread the cards so that they can only take a middle card,
and then guess it. Finally, do the same for the bottom. Or even better, have the spectator choose
three cards and name them all. The best way to do this is to have the cards alternate and just have
them take three consecutive cards. This deck is also good if you are someone who always uses
duplicates or do packet tricks where you need multiples of the same card.
