Concept: Every sleight Olly can perform is connected to his body in one way or another. When he sneezes a card pops out of the deck. When he yawns, a card goes into the deck. If he is to clap his hands, a torn card is restored. If he farts, the deck shuffles itself. If he burps, the deck un-shuffles itself. If he moves his ears, the chosen card is controlled to the top.
Sketch
Setting: FISM Championship look-alike stage.
The performer announces that he will perform his entire routine without touching the deck at all.
What follows is Olly creating a sort of song made out of human noises, animal sounds and all different types of sounds made out of interacting with objects. In contrast to the horrible show of skill(?), the deck is seen performing acts of magic all by itself,
Ideas
During the performance you can have a fly go in Olly's mouth, making the deck do something that it isn't supposed. This could be a dark way to end the sketch, with Olly dying and the deck still performing, because Olly is still making all sorts of noises.
This can be shown in separate timelines. One when he is winning the National Contest, one with the European Contest and the final one FISM, each act evolving from the previous one in absurdness.
The final act can feature 12 individuals on stage connected to the same deck, creating an opera of sounds while at the same time giving birth to the most magnificent show ever seen.
