Effect

The magician presents the spectator with a beautiful and ornate wooden box. He removes the lid and shows that the box contains a single key. As he removes the key and hands it to the spectator, the magician says that this key will open the door that separates what is real from what is imaginary. The magician places the lid back on the box.
 
The spectator is then asked to imagine a deck of cards, as this will be needed for the next trick. With a wave of his hand and a shake of the box, the magician removes the lid of the box to reveal that a deck of cards has miraculously appeared inside of the box!
