* 603.6. Trigger events that involve objects changing zones are called “zone-change triggers.”
* Many abilities with zone-change triggers attempt to do something to that object after it
* changes zones. During resolution, these abilities look for the object in the zone that
* it moved to. If the object is unable to be found in the zone it went to, the part of the
* ability attempting to do something to the object will fail to do anything. The ability could
* be unable to find the object because the object never entered the specified zone, because it
* left the zone before the ability resolved, or because it is in a zone that is hidden from
* a player, such as a library or an opponents hand. (This rule applies even if the object
* leaves the zone and returns again before the ability resolves.) The most common zone-change
* triggers are enters-the-battlefield triggers and leaves-the-battlefield triggers.
