This deck is basically an INVISIBLE DECK with a BRAINWAVE TWIST.
The spectator names any card while the performer removes the deck face-up (from a BLUE box) and slowly spreads the cards until a face-down RED backed card is seen -- this card is turned over to reveal that it's the spectator's named card. During this reveal moment, the deck is seen as a blue-backed deck, thus the spectator's card is the only red-backed, face-down card in a blue-backed deck.
You can think of this deck as a "FACE-UP BRAINWAVE DECK", no need to mentally count-over to the target card's position. With this deck you can openly find and view the target card [BLUE] in order to locate the face-down partner [RED].
Available in Bicycle Rider Backs -- Made with the Mimesis "FLUID" Separation formula.
Also marketed in the past as: Solari Brainwave Deck, Turbo Invisible Deck.
