You spread the cards face up onto the table, showing there is no Ace of Spades in the deck. You then take the Ace of Spades (The Magic Ace) out from an envelope, and place it face up into the face down deck. A quick snap of the fingers and when you spread the cards again, the Ace of Spades has vanished. It is now back in the envelope! You turn the whole deck face up and go through every single card showing the Ace of Spades really has gone from the deck and back into the envelope. Then you seal the Ace of Spades into the envelope, and with just a snap of the fingers the Ace of Spades has now completely vanished from INSIDE the sealed envelope. Now comes the finale, you spread the cards face down onto the table, and there, face up in the middle rests the Ace of Spades.

Two super clean, super visual vanishes, and two great reappearances.

This is the Magic Ace.
