410.2.

Whenever a game event or game state matches a triggered ability's trigger event, that ability triggers. When a phase or step begins, all abilities that trigger "at the beginning of" that phase or step trigger. The ability is controlled by the player who controlled its source at the time it triggered. It has the text of the ability that created it, and no other characteristics. The ability doesn't do anything when it triggers, but it's automatically put on the stack by its controller as soon as a player would receive priority.

When a phase or step begins, all abilities that trigger "at the beginning of" that phase or step trigger. The ability is controlled by the player who controlled its source at the time it triggered,unless it's a delayed triggered ability. The controller of a delayed triggered ability is the player who controlled the spell or ability that created it. The ability doesn't do anything when it triggers, but it's automatically put on the stack by its controller as soon as a player would receive priority. Each triggered ability on the stack has the text of the ability that created it, and no other characteristics.
