If you've ever seen a rap battle (or Eminem's semi-biopic movie 8 Mile), then you have at least some knowledge of what happens at these types of events. This video, uploaded by Tobias Levin, comically shows what it would be like if a cardistry competition happened like a freestyle rap battle.

I have to say, I didn't even know cardistry (also know as card flourish) was an actual thing. Although practiced by a large number of magicians, it is quickly garnering a following outside the magic circles and amongst young people.
