In a Commander game, a commander that has been exempted from the procedure that restarts the game won’t begin the new game in the command zone. However, it remains that deck’s commander for the new game. See rule 903, “Commander.”

At the end of a subgame, each nontraditional card not in a supplementary deck that began the subgame in a supplementary deck is turned face down and put on the bottom of that deck. Then each player moves each of their supplementary decks from the subgame command zone to the main-game command zone and shuffles it.
