This is a nice little item that is always on you. I carry it on my "Key Deposit" (Jay Sankey) keyring.
I'm not judging, because it is a lovely piece, but the reveal isn't as fast as it is in the trailer. (Unless mine is faulty!)
I normally ask someone to hold the Swag tightly, "because I AM going to steal it from you". Turn to another spectator and perform Jay Sankeys Key Deposit, then turn back to first spectator, remove a pack of cards from my pocket and have them cut the pack (Cross Cut Force) with their empty hand and finish with me telling him/her I did steal it and switched another one with my predictions back into their hand.
