This is the best handling of a misprint I've ever seen. According to the KS updates one of the cards in Jay's picture was misprinted. In the past, creators either ignore it or send a replacement. In this instance they created magic tricks, sent even more extra cards to do multiple routines, and sent everyone video instructions on how to preform the tricks. Boy am I happy I backed these!
When I saw the update of the error I looked at the uncut sheet on the campaign page. It had the 4oC with 5 pips so they either planned this all along or got USPCC to print another sheet to fix the error and add extra cards. Nice either way!
