Wow! What a cool way to reveal a prediction!
The spectator shuffles the deck. Two Jokers are introduced and used to randomly select 2 cards. However, when the spectator reads the fine print on the Guarantee Joker he discovers... the two selected cards were clearly predicted in advance and actually printed on the card!
Here's what you get:

 
TWO genuine Bicycle cards, one red, one blue, each with different guaranteed selections.
 
An amazing effect that is really easy to perform.
 
A trick that finishes clean - have everything examined and leave your audience talking about... YOU!
