unless their deck matches. The promise of being able to use a spectator's deck is misleading. If
someone has a generic one way deck from a tradeshow with a different face design, for example, or a
bridge sized deck, then you can't do the trick unless you made special arrangements in advance to
match this deck. Unfortunately, my spectators don't use bicycle decks, which I use. They use
whatever is cheap or whatever was given to them.
Other than that, it's a great trick.
But to clarify, unless the deck that is handed to you is typically the deck design that you
normally use, then you can't use the spectator's deck.
