/**
* If the land Chained to the Rocks is enchanting stops being a Mountain or
* another player gains control of it, Chained to the Rocks will be put into its
* owner's graveyard when state-based actions are performed.
*
* Chained to the Rocks's ability causes a zone change with a duration, a style
* of ability introduced in Magic 2014 that's somewhat reminiscent of older
* cards like Oblivion Ring. However, unlike Oblivion Ring, cards like Chained
* to the Rocks 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 Chained to the Rocks
* leaves the battlefield.
*
* If Chained to the Rocks leaves the battlefield before its triggered ability
* resolves, the target creature won't be exiled.
*
* Auras attached to the exiled creature will be put into their owners'
* graveyards (unless they have bestow). Equipment attached to the exiled
* creature will become unattached and remain on the battlefield. Any counters
* on the exiled creature will cease to exist.
*
* If a creature token is exiled, it ceases to exist. It won't be returned to
* the battlefield.
*
* The exiled card returns to the battlefield immediately after Chained to the
* Rocks leaves the battlefield. Nothing happens between the two events,
* including state-based actions.
*
* In a multiplayer game, if Chained to the Rocks'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.
