S.L.O.B. by Simon Lovell

Important Note From Magictricks.io. we will explain to you how the trick is done (how to preform it) 

in the performance only the back of card is changed but you can add (pick me) word to the card

SLOB stands for Simon Lovell’s Oblique Brainwave! In effect, a spectator deals through the deck face up, stopping on a card he feels good about. This card is instantly shown to be of a different color back from the rest of the deck. He can even take the card away as a souvenir if he wishes!

There’s no wax, rough or smooth, flaps, or sleight of hand. It’s another great, easy Simon Lovell effect.
