The magician can make the whole deck of cards to ice, well it’s not really ice, the deck of cards just turn in to glass. However, this trick is not easy to do, you have to come up with a solution to change it when nobody sees you.
What a lot of magicians (who are using this) do is that they let the spectator chose a card, then the spectator looks at the card, and while they do the magician turns the back around the spectator to change the whole deck to the glass deck. And then he can perform it. This trick has also been used by many magic mentalist.
Notice before you order, you have to practice so you’ll become really good with it.
