Rule 704.5w
Official source text from the 26 September 2015 Rules release
In an Archenemy game, if a non-ongoing scheme card is face up in the command zone, and it isn’t the source of a triggered ability that has triggered but not yet left the stack, that scheme card is turned face down and put on the bottom of its owner’s scheme deck. See rule 904, “Archenemy.”
