but according to the rule C.R. 726.1

Under what is now C.R. 726.1, a "game that is restarted immediately ends. No players in that game win, lose, or draw that game. All players in that game when it ended then start a new game" in accordance with C.R. 103. However, all "Magic cards involved in the game that was restarted when it ended, including phased-out permanents and nontraditional Magic cards, are involved in the new game" (C.R. 726.2). C.R. 726.2, though, doesn't apply to non-card objects, such as emblems.
