The Classic Pass is most commonly used to control a card to the top or bottom of the deck, but can also be used as a fun little color change as well. You just have to be extra careful about it because unlike other color changes, you're moving a lot more cards to achieve this effect. 51 cards to be exact. This means that the stakes are higher and the heat is on you from the moment you begin the routine. Not to worry though, with a bit of practice, you'll get the hang of this in no time.
