Hive Mind by Matt Baker

A prediction is written down on a piece of paper but unlike most effects that begin this way, you let a spectator write the prediction. They choose a couple others to be involved and the spectator even chooses the outcome for each spectator. A lot of decisions are made and at the end everything is 100% correct. This is a mind blowing experience for the spectator that they help create.

-Uses ordinary items(coins,piece of paper)
-Works 100% of the time
-No difficult moves
