Rule 800.4d

If an object that would be owned by a player who has left the game would be created in any zone, it isn’t created. If a triggered ability that would be controlled by a player who has left the game would be put onto the stack, it isn’t put on the stack. Example: Astral Slide is an enchantment that reads, “Whenever a player cycles a card, you may exile target creature. If you do, return that creature to the battlefield under its owner’s control at the beginning of the next end step.” During Alex’s turn, Bianca uses Astral Slide’s ability to exile Alex’s Hypnotic Specter. Before the end of that turn, Bianca leaves the game. At the beginning of the end step, the delayed triggered ability generated by Astral Slide that would return Hypnotic Specter to the battlefield triggers, but it isn’t put on the stack. Hypnotic Specter never returns to the battlefield.
