Fan the deck and show that all the cards are different.
Have a spectator select a card and put it back in the middle of the pack. Snap your fingers and it's back to the top. Then, like a "Svengali" deck you riffle the cards and the entire deck changes to the selected card.
This is just one great effect you can do with this deck.
This is also a great Forcing Deck because you can show all the faces to be different yet the card they select will always be your f"force" card.
