text: Colossal Whale's ability causes a zone change with a duration, a new style of ability that's somewhat reminiscent of older cards like Oblivion Ring. However, unlike Oblivion Ring, cards like Colossal Whale have a single ability that creates two one-shot effects: one that exiles the creature when the ability resolves, and another that returns the exiled card to the battlefield immediately after Colossal Whale leaves the battlefield.
