Alright, I'm looking for the name of an effect I was taught years ago. I don't even really know how to describe it without revealing its setup, but I'll do my best. It's a packet trick and I'll describe it using my set up. I will describe it based on how it appears to the audience, not necessarily how it "really" is.

1 blue-backed King of Diamonds is removed from the bottom of the face up packet and placed on the table. The remaining 4 cards are shown (counted) to be 9 of Clubs. They're turned over and the backs are shown (counted) to all be red. The King is placed on the face and the last 9C is removed and placed on the table. The packet of cards are now shown (counted) to be 4 KDs and turned over and shown (counted) to be blue backed.

6 cards in total are used. Some duplicate cards (duh, "4" 9's and "4" Ks!) are used, but no other gimmicked cards are employed.

If anyone thinks they might know what this effect is please help me out!

Thanks,

"The king and his comrades"

Just a thought

Andrew,
There are so many packet effects and it would be really tough trying to narrow that one down. Can you give any more info on it ? It does sound similar to an effect called Marked, but not sure if the faces change in that one.
