cr:3.0.9a

An ability that triggers when an object moves from one zone to another still references the new object, as long as the object remains a public object.

Example: Merciful Retribution has the text “Whenever an aura or attack action card you control is destroyed, . . . If it’s a non-token Light card, put it into your hero’s soul.” If a non-token Light card in the arena is destroyed, it moves to the graveyard and becomes a new object. However, because Merciful Retribution triggers on the object moving to the graveyard (as part of its destruction) it still references the new object it becomes in that zone for the triggered-layer it produces. If the non-token Light card moves to another zone or becomes private before the layer resolves, the triggered-layer loses that reference.
