I gotta say, this trick KILLED at a few casual settings. People were amazed by how not once but
twice(!) the cards matched. It's easy to perform and even easier to learn! The only thing I'd say
that needs improvement is the awkward downtime when you do the calculator move. Derek says to fill
it in with a joke about tinder, but I know most of my friends, and that is not a joke that would be
laughed at. I usually say that I'm playing Angry Birds instead, but that only fills for a few
seconds. The time it takes to do the move is approx. 5-10 seconds for me, and if that is not cloaked
by chatter, then it will become boring and suspicious very quickly. Overall, great trick and the
downtime will, I'm sure, be easily overcome by creative magicians.
