Craig is a huge fan of collectors (he actually collects them!) This is one of his favourites. Unlike the common use of collectors routines, this one doesn't have the series of controls and displacements you would usually see. You take the four kings and they are isolated within the box at the very beginning. Once the three cards have been picked you can immediately show they are in-between the collectors cards. For workers, this trick is an absolute dream. The bottom line is that this is very different to collectors. It's a shuffled deck of cards in use with no gimmicks, no extras, and can be used at anytime & anywhere.
