Street Magicians and demonic assistance

What kinds of Demons and spirits assist the widely popular street magicians like Dynamo (and more recently) David Blaine?

They seem to make a point of NOT evoking, harkening back or referencing any demonic symbols or sigils, keeping their work completely secular and dismissable.

These kinds of magicians (supposedly LHP as they are effecting their physical world) are becoming very popular on America’s Got Talent and Penn and Teller’s Fool Us.
One contestant of AGT even told the judges he gets assistance from his spirit friend he calls Desmond.

Do any demons specialize in public theatrics, and impossible slights of hand?
