cr:1.9.2c

If an event involves two or more players performing an instruction, it is a multi-event where each player performs that instruction in clockwise order as an individual event, starting with the turn-player.[1.1.6] If the event was produced by an effect, each player performs that instruction starting with the controller of the effect instead.

Example: This Round’s on Me has the text “Each hero draws a card,” which when resolved produces a multi-event that instructs each player to draw a card. This starts with the player who controls This Round’s on Me as it resolves on the stack.
