I love effects that have multiple "magical moments," and John Bannon's Twisted Sisters has THREE of
them, with each one more impressive than the last. There is one easy slight involved, and the DVD
teaches a "slightless" version as well.
While the cards aren't fully examinable, I've found
that the cards that take all the heat, after the final magical moment, are not the ones you don't
want them to examine closely. In fact, by the time that last moment occurs, the gaffs are back in my
pocket and I'm clean.
This is my second purchase of Twisted Sisters, as I wore out the
cards from the original version. While it always twerks me a bit when packet tricks don't have
refills and you have to re-purchase the whole thing, it's only $15 and well-worth it.
