Concept: Through a cord you are able to connect anything to a deck of cards and manipulate it through this.

Sketch: A medic is confronted with having to fix a boys broken back on the spot. He quickly pulls out the cord from his inner pocket, rests assured with his deck in his hand and connects the cord to the boys back.

Then watches the deck as it arranges itself in a awkward shape. "Hmmm I see where the bones have split. No worries, I got this." then proceeds to cardistry the fuck out of the boys back problem into a healthy condition.
