I bought Twisted Sisters like 5 years ago when I first got into magic, and it instantly became one of my favorite tricks. However, I didn't really perform it much because it was gaffed and I don't like carrying around stuff with me especially if it can't be examined. So Twisted Sisters went into the magic junk drawer.

John Bannon has done what magicians were waiting years for - create a version of Twisted Sisters that is examinable.
Effect: Same exact as Twisted Sis. but with aces.
Slights: Only one slight is used, and it's a slight that every magician knows (and if they don't - John teaches it in depth).
Difficulty: The hardest part is remembering the patter. You are gonna have to remember some patter, but it's quite simple to remember.
Practicality: EXTREMELY practical. You can so this trick for close-up, walkaround, and stage (if you have a projector bec. the cards are small - but you can always use jumbo cards).
Set UP/Reset : 3 seconds each.
Reactions: Worth a LOT more than $11.25
DVD: Very well made. And you get an AWESOME bonus effect which kills people!
Conclusion: If you don't have Duplicity, buy it. NOW. You won't regret it.
