Hello, I am very new to magic, and this forum. I'm just wondering if there is a trick out there that someone performs like this: Person 1 selects a card at random, no forces, no tricks and you control a separate card into their hand. Lets say they pick a 2 of spades at random and you give them a separate card without their knowledge to hold to in between their hands. Then you ask them to think of a card, any card, and that card will be the card one of their colleagues (Person 2) picks, lets say they say the 4 of hearts. You force the original card that was picked into Person 2's hands and they hold onto it tightly, so now Person 2 has the 2 of spades. You then ask them both to look at the cards in their hand and it's reversed so person 1 who thought they had the 2 of spades now has the 4 of hearts, and person 2 who thought they were given the 4 of hearts has the 2 of spades. I cannot perform this. I'm looking to find a way to control a card that someone will think of after the fact without actually bringing the card they have back into my hand for a switch or something. I don't even know if this is possible. Can anyone guide me in the right direction, to methods, videos, books or whatever else? Thanks!
