Here's why:
* Magic is an illusion: Criss Angel's performances rely on tricks, sleight of hand, and elaborate stagecraft. These techniques are designed to deceive the audience and create the illusion of the supernatural.
* "Black magic" is not a real thing: "Black magic" is a concept often associated with superstition and belief in the occult. There is no scientific evidence to support the existence of such practices.
* Angel's focus is on entertainment: Criss Angel's career is built on entertaining audiences with illusions and mind-bending tricks. He has never claimed to practice any form of real magic or witchcraft.
Ultimately, judging whether or not someone uses "black magic" is a matter of personal belief. However, it's essential to remember that magic as performed by illusionists like Criss Angel is simply an elaborate form of entertainment.
