Hero of Bretagard — ruling 1

Hero of Bretagard has recieved an update to its Oracle text. Specifically, its triggered ability doesn't care which player is exiling the cards and permanents. Cards put into exile from your hand for any reason, such as the foretell ability, cause the ability to trigger, and permanents exiled from the battlefield cause it to trigger if you controlled the spell or ability that exiled them.
