Editing Trick deck (section)

===Brainwave deck===
The Brainwave deck is a lesser-known deck which is gaining in popularity, it operates on a principle similar to that of the Invisible Deck, but has vastly improved on it. With the cards still in their box, the magician asks a spectator to name a card. The magician pulls the deck out and fans the cards face down, then spreads through the deck until a single face-up card is discovered, which turns out to be the spectator's card. For the grand finale the magician explains that he or she actually knew ahead of time which card the spectator would select, rather than having secretly turned it over during the performance. He or she then proceeds to prove this by turning the spectator's card over and revealing that the card in question features a different backing pattern than every other card in the deck, suggesting to the audience that the magician may possess powers of [[extrasensory perception]].

An inverse handling of the Brainwave deck is the X Deck, originally invented by [[Jay Sankey]] and identical to the Invisible Deck, but with the odd cards having an X on them. Both decks are meant to convey the idea that the magician did not perform the intended effect through the use of [[sleight of hand]].
