Recently found in England was this Arrow #11 magic deck.
It was used for a very basic magic trick since all the cards are the three of spades. You would pull out the deck, face down, ask someone to pick a card, memorize it and place it back into the deck. After shuffling you pull out one card and show it to the person and it's a perfect match. Then another similar deck is switched in for another trick. The deck can be pocketed after the force as a logical handling of your routine; e.g. you need a pencil from that pocket.
In general: yes, it works.
Forcing Decks are known as a type of Mechanical Deck of playing cards used to force a spectator to select a particular card, which the magician knows in advance.
