I do a number of different effects involving matching ESP cards, which may look a bit similar, but
want a range of options for presentations, so this is a valuable addition. If I'm with a group that
may have seen a different effect, it lets me avoid repeating exactly the same effect for them again
too soon. The handling and approach is good although I'm weighing thoughts about alternatives to the
one sleight needed -- others have suggested alternatives as well. I personally prefer an
audience-member-as-psychic approach for all of my effects, and it's easy to turn this presentation
around. Instead of having the audience member think of a symbol and trying to guess it, my
presentation will have ME looking at a symbol and putting it down and asking the audience member to
try to get an impression of what symbol is in MY mind and putting down that symbol. I have found
that this approach always eliminates the challenge response of a spectator trying to catch the
performer out and make the effect fail, instead giving the spectator the motivation for the effect
to succeed, and they get the "win" when it does. Participants never feel like the performer has
one-upped them or put them down in any way, and the audience still knows who is responsible for the
success of the effect.
