OCD Deck by Andrew Gerard and SansMinds - Trick
This deck does everything for you and you can even perform it surrounded. Imagine having the spectator holding a shuffled deck of playing cards along with their signed card somewhere in the deck. They shake the deck, and the entire deck, including their signed card, rearranges itself back into new deck order; Ace to king. It's a jaw dropping miracle that you and your audience are going to have a lot of fun with.
