This is without a doubt my favorite card routine seconded only by Shawn Farquhar's, signed and
sealed, also known as Back in Time by Cyril Takayama.
I love it. Magic doesn't get more
magical than this, the trick is a 3 part trick:
1- reveal that your 3 predictions match the
spectator's card;
2- explain how they where all from different colored decks, changing the color
of your predicted cards;
3- then, change the color of the entire deck, leaving in front of you 5
different colors
The sequence of the routine escalates from "what the hell," to "holy
sh*t," to "WHAT THE F*CK." If performed correctly at a nice and slow pace, letting each step sink
in, it will be killer.
Only problem with the routine is you aren't left clean, however, if
you take your time with each each step, then the spectator will want to at most inspect the deck
(which is clean) and you can quickly put away the other cards and ---move on to another effect
before anyone asks about the other cards---
Please take your time with this routine and
figure out a patter that you think suits it best because it truly is an amazing effect.
