Think of a Card

[DalyTM]

I saw a trick once where someone made people choose 4 cards , and then he told them to think about one of the chosen cards , then he would guess what card they chose .
What's this magic trick called?
Because I would want to buy It

This isn't something unique to you but people tend to leave out very important parts of magic tricks so without a video or a more detailed description, it's hard to help you man. Hopefully someone will know what you're talking about tho!
