Instant Switch is the evolution of modern times, Henry Evans opener effect of his FISM Winner act.
A very visual opener with two decks, which, its interesting part, is what's hidden on the effect structure, since it allows you to clarify with real shuffles that the red deck was truly shuffled and immediately after finishing the effect, the red deck will be completely in the order that we desire (as it could be from as to king, or a mnemonical, etc.)
That's why besides this being a visual and direct opener, it leaves a great field with good conditions for the effects that proceed after.
Effect: Two decks are shown (one blue back and one red back). The red deck is riffled shuffled multiple times while the magician talks about the impossibility of knowing the order of the cards after those shuffles.
The magician continues to explain to the audience that some gamblers are able to change one whole deck for other without anyone notice to show this, the red deck is placed under a handkerchief and the magician takes the blue deck out of the card box.
In an instant, in front of everyone's eyes, the blue deck transforms into the red deck and under the handkerchief now is the blue deck.
It includes: - A double back deck blue/red
- A flap Joker that changes backs from blue to red
- A handkerchief
