I have been doing a card effect for the last 20 years where I start with one printed card and 5 blanks. I then proceed to print one card at a time. Front first until I get 4 cards printed. I then print the back but all 5 cards are now all changed to another card.
I had seen a guy a while back, 20 years, who use to do a good Wild Card routine and some others similar.
I then tried my own version of his printing effect and came out with this.
Before I start selling it I would like to know if it looks like something already "out there" ...
