Who is Mentalist from What Have You Lost? and what is their importance?

The mentalist works with playing cards. He palms his cards while the audience applauds..... smiling but also frowning a bit too. Shaking his head like something is wrong, he sees that the cards cut and nothing left. He looks around as if to be rid of his gift, willing to wish it on anyone, but he is old news and the audience is already watching the next performer.
