I really love this effect... I found a handmade from Eugene Burger from 20 years ago. I wondered why this blue pack of cards was in the red case. Pulled it out and it worked like a charm. Fooled a very very smart laymen buddy, he slightly caught on to the magicians choice part, for a second on the first question, but then from there, its pretty fair. Really just a great piece of entertainment with can pretty much be done at ease and focus on the presentation. It's undeniable and unbelievable. The way you proudly hand out the cards at the end, scream the cards are normal. An oldie, but a goodie!
