I am a huge believer in the principal of minimizing the actual and apparent effort in a trick: do as
much work with your brain in advance as possible, then work as hard as you can on that which is left
to do.
There's no better examplar of that principle than Mahdi. The work he has put into
some classics of magic, both on the execution, audience management, and scripting, is outstanding.
If you don't come away with at least one idea that changes the way you think about
your magic, you probably weren't paying attention 😀
