Xerox Deck (Red) by Iñaki Zabaletta and Vernet - Trick

With Xerox deck you can show the most visual and amazing multiple transformation of an entire deck of cards.

Imagine:
You show a regular red back deck with indifferent cards on the faces. You only have to add a selected card from a blue deck, let's say the three of spades, and instantly all the cards are three of spades. If that's not enough, all the backs change into blue. After this jaw dropping double transformation, with only taking out the selected card (the three of spades), the deck goes back to regular, with red backs and indifferent cards on the face.

No fancy moves.
Very easy to do.
Instant reset.
Looks like 'trick photography.'
You can spread and show very freely the cards all the time.
4 ultra visual changes in 1 deck.
No double index cards.
