Card Castles have long been a staple of manipulation acts.
After you produce some cards, toss them on the table. Cover these cards with a large Silk. As you lift the Silk you produce a Castle of Cards!
The performer drops some cards on to a tray. He covers these with a handkerchief, which is then lifted away to reveal the cards in the form of a large Card Castle. Use it as an effect by itself, or as a big visual climax to other card effects.
