Unfortunately, the rules text for each version of Knight of the Kitchen Sink, Very Cryptic Command, Sly Spy, Garbage Elemental, Ineffable Blessing, & Everythingamajig are identical, though they have the flavor text correct where applicable. Also, Very Cryptic Command has 49a and 49b switched, and Secret Base has 165a and 165b switched, but I've sent a message to their staff in the hopes of getting all of this corrected.
