Explanation is a good half hour and well presented. At the end, David also provides suggestions to
handle "what if" scenarios.
What is important here is that the effect does not require any
advanced skills beyond a partial false shuffle. It would be usable by walkaround performers, with
reset taking 30 seconds or less; however, chosen cards will always be the same. Another cool aspect
- the magician can use one of the decks for other tricks (in this presentation, the red deck) and
then bring out the blue deck for the Follow the Leader routine.
This is one of those
effects that reminds me of Out of This World. Not the method but rather the effect - mindblowing,
yet very simple to perform.
