KODOKUNA by Joseph B

Here we play with an imaginary deck.
In this effect the Magician ask the spectator to name any four cards. Than the spectator choose one among these four.
The card named will be the only visible cards in a completely blank deck!
It is a really strong effect, it seems like real magic that will leave the spectator astonished.
NO rough and smooth
NO sticky stuff
