Cast Out

If Cast Out leaves the battlefield before its triggered ability resolves, the target permanent won't be exiled.

If a token is exiled this way, it will cease to exist and won't return to the battlefield.

In a multiplayer game, if Cast Out's owner leaves the game, the exiled card will return to the battlefield. Because the one-shot effect that returns the card isn't an ability that goes on the stack, it won't cease to exist along with the leaving player's spells and abilities on the stack.
