Rule 723.1 · Controlling Another Player
Some cards allow a player to control another player during that player’s next turn. This effect applies to the next turn that the affected player actually takes. The affected player is controlled during the entire turn; the effect doesn’t end until the beginning of the next turn.
Subrules
Multiple player-controlling effects that affect the same player overwrite each other. The last one to be created is the one that works.
If a turn is skipped, any pending player-controlling effects wait until the player who would be affected actually takes a turn.
