KILL WITH A SINGLE SHOOT by Joseph B

This effect is a killer as you can see from the title.
You can borrow the deck from your spectator and the most important thing is that you can do it completely impromptu.
The magician finds the spectator chosen card under impossible conditions, in one shoot, using a lucky card.
As always it is a Fooler, also for fellow magicians.

NO GIMMICK
NO MARKED CARDS
