I have a deck of cards that are all 2 of clubs, but every back is different. Included as well are two two of diamonds with a red back and two two of hearts with a red back. I know the premise is the spectator places the cards into the deck and finds the mate, but I can't for the life of me remember how it works, or what it's called. It's going to drive me insane! lol. Anyway, if someone knows the name or method I'd appreciate a PM. Thanks a million.

I remember now that Lennart Green uses this deck in his routine called "Stolen Cards" and I know the method, but I'm still looking for the original name.

Kaleidoscope Cards. Finally. Thanks.
