Díaz’s best routine was performed alone to a peppy Jacques Brel song. Breathlessly, Díaz manipulated a ball (a tribute to Cardini’s classic billiard ball routine), many cards, even his own right shoe. His hands would be empty. His mouth would be empty. You would swear to it on any available Bible. Then they would be full, cards raining to the floor. He sent a few cards whizzing through the air in a way that reminded me of Ricky Jay, the scholar and magician, who died in 2018. I may have teared up a little. This was Díaz’s simplest sequence and also his most beautiful. Who needs a helicopter when you can make magic like that?
