Red Medicine by Mark Calabrese

1. You BORROW A DECK of cards if one is available. Otherwise grab your own ORDINARY pack.

2. You then ask someone to name ANY card. They take the deck of cards under a table or behind their back, and BY INSTINCT ALONE remove ANY CARD from the deck, turn it face up and cut it back into the deck. 

3. The cards are spread, and the only face up card is THEIR THOUGHT-OF CARD.

Works with ANY deck of cards. Everything can be completely examined.

Multiple methods taught.
Easy to do, they do all of the work.
The deck can be borrowed.
