text: Brain Maggot's ability causes a zone change with a duration, a new style of ability that's somewhat reminiscent of older cards like Tidehollow Sculler. However, unlike Tidehollow Sculler, Brain Maggot has a single ability that creates two one-shot effects: one that exiles the nonland card when the ability resolves, and another that returns the exiled card to its owner's hand immediately after Brain Maggot leaves the battlefield.
