Pinnacle by Brian Caswell

Trilogy was a ground-breaking and best-selling effect. Pinnacle is a mixture of Trilogy and Brian's other best seller, Cataclysm. Imagine showing a deck of cards. Each card has a number from 1-52 on the back. Your spectator names 3 cards (there are no high-low or odd-even restrictions). You remove the named cards from the deck and place them face up on the table. 

You now direct your spectator to a prediction you have made -- the numbers on your prediction match the numbers on the back of the cards! 

OK, so what's new, I hear you ask? Well, get this, your prediction is in full view before you even start the effect. You can text it to your spectator, have it written on a business card, on a photo or even on your social media page. YES, there is only ONE prediction!
