JP Vallarino & Yuri Kaine - Killer Card Case

A devastating effect, the kind of flashy visuals that we would like to see more often. 

(Effect)
A chosen card is signed and lost in the deck. 

In one gesture, the magician vanishes all the faces from the cards...leaving them all completely blank for the rest of the effect. Even the chosen card has vanished as well...

The magician removes a card case from his pocket (the card case could have been on the table in full view from the beginning). Due to the fact that the top of the card case is transparent, the spectator can clearly see it is completely empty. 

The card case is put on the mat to prevent any sleights of hand. 

With a simple flick of the card case, the selected card instantly appears in the box. 

The spectator himself removes his card from the box with the signature on it. Everything is totally examinable!
