Editing Trick deck (section)

===Invisible deck===
The invisible deck is one of the best known card tricks. [[Joe Berg]] created the Invisible Deck in the 1930s, originally calling it the Ultra Mental Deck. Often mistakenly credited to [[Dai Vernon]], [[Don Alan]] or Eddie Fields, the most-used presentation of an "invisible" deck of cards was invented by [[J.B. Bobo]].

The trick's title stems from the classic presentation of this effect, in which the magician hands the spectator an imaginary, or "invisible" deck. On being handed the deck, the spectator is asked to mime the acts of removing the cards from their case, shuffling them, spreading them face-up on the table, freely selecting a card, replacing it face-down among the other face-up cards, and returning the deck to its box.

At this point, either the spectator keeps the imaginary deck while the magician removes the real deck from his pocket, or the spectator hands the imaginary deck to the magician, which suddenly becomes real in the magician's hands. Michael Close also uses a handling in which the invisible deck is tossed back into a paper bag, whereupon it becomes real and visible.<ref>{{cite AV media|title=Ultimate Workers, Vol. 1|author=Michael Close|publisher=L & L Publishing|year=2003}}</ref> The magician then asks the spectator to name the card they selected, removes the deck, face-up, from its box and spreads the cards to show one face-down card. The spectator removes the card to find it is the one they named moments earlier.

In the more comedic version of the routine, more focus will be drawn to the part of the effect where the spectator is handling the cards. Often, the magician might criticize the spectator's card-handling abilities, or remind him or her to take the cards out of the case before trying to shuffle them.

A more serious routine can be performed, which focuses more on the magician's mindreading abilities and the fact that the spectator had a completely free choice of card. The magician could hand the spectator a box of cards to hold, ask him or her to think of, and concentrate on, any card in the deck, and then to name it. The spectator then hands the box back to the magician and the trick completed as before.

The invisible deck is prepared by arranging a normal deck so that all the even cards face one way and the odd cards the other. Cards are then slightly glued or stuck together into even-odd pairs, face out. When the spectator names his or her card, the deck is extracted from the box with the chosen [[Parity (mathematics)|parity]], even or odd, facing the magician. The magician then fans out the cards until he see the spectator's, which will be facing him. Applying a small amount of pressure, the card is split from its opposite member, revealing the back of the card for the spectator to see and choose.<ref name=invisible/>

The deck can be bought from magic dealers. It is also possible to construct the deck using a regular deck and additional materials from department stores.<ref name=invisible>{{cite book|title=Magic: The Complete Course|author=Joshua Jay|publisher=Workman Publishing|year=2008|isbn=978-0-7611-4987-3}} p. 85.</ref><ref>{{cite book|title=Presenting and training with magic!: 53 simple tricks you can use to energize any audience|author=Ed Rose|publisher=McGraw-Hill Professional|year=1997|isbn=0-07-054040-3}} p. 165.</ref>
