The backs of 3 of 4 blue backed cards removed from a 'blue' deck turn into a fourth selected card.
Then then the backs of three of the cards change to different colors and finally the balance of the
deck turns red.
The only issue for me was that one of changes was from BLUE to BLACK and is
not very noticeable. It is beyond me why they would make it GREEN for example? If you are printing a
gaff set, then why not make the contrasts as bold as possible?
Otherwise... great routine
