Rule 904.4
Official source text from the 4 October 2019 Rules release
At the start of the game, the archenemy shuffles their scheme deck so that the cards are in a random order. The scheme deck is placed face down next to the archenemy’s library. All scheme cards remain in the command zone throughout the game, both while they’re part of a scheme deck and while they’re face up.
