You can use this trick in flash effect, but you can if you want to flesh out the presentation a bit, for example by having a card chosen, but by the time you find it, you show a bad card... Your audience thinks you made a mistake!
But at that moment, you ask for the name of the card that has been chosen, you throw the card you are holding in your hand in the air and instantly and on sight, it turns into the chosen card. !
The gimmick is wonderfully manufactured, it is supplied in Bicycle Rider back quality!
