400.7. An object that moves from one zone to another becomes a new object with no memory of, or relation to, its previous existence. There are nine exceptions to this rule:

400.7a Effects from spells, activated abilities, and triggered abilities that change the characteristics of a permanent spell on the stack continue to apply to the permanent that spell becomes.

400.7b Prevention effects that apply to damage from a permanent spell on the stack continue to apply to damage from the permanent that spell becomes.

400.7c An ability of a permanent can reference information about the spell that became that permanent, including what costs were paid to cast that spell or what mana was spent to pay those costs.

400.7d Abilities that trigger when an object moves from one zone to another (for example, “When Rancor is put into a graveyard from the battlefield”) can find the new object that it became in the zone it moved to when the ability triggered, if that zone is a public zone.

400.7e Abilities of Auras that trigger when the enchanted permanent leaves the battlefield can find the new object that Aura became in its owner’s graveyard if it was put into that graveyard at the same time the enchanted permanent left the battlefield. It can also find the new object that Aura became in its owner’s graveyard as a result of being put there as a state-based action for not being attached to a permanent. (See rule 704.5m.)

400.7f If an effect grants a nonland card an ability that allows it to be cast, that ability will continue to apply to the new object that card became after it moved to the stack as a result of being cast this way.

400.7g If an effect allows a nonland card to be cast, other parts of that effect can find the new object that card becomes after it moves to the stack as a result of being cast this way.

400.7h If an effect causes an object to move to a public zone, other parts of that effect can find that object. If the cost of a spell or ability causes an object to move to a public zone, that spell or ability’s effects can find that object.

400.7i After resolving a madness triggered ability (see rule 702.34), if the exiled card wasn’t cast and was moved to a public zone, effects referencing the discarded card can find that object.

700.7. If an ability of an object uses a phrase such as “this [something]” to identify an object, where [something] is a characteristic, it is referring to that particular object, even if it isn’t the appropriate characteristic at the time.

Example: An ability reads “Target creature gets +2/+2 until end of turn. Destroy that creature at the beginning of the next end step.” The ability will destroy the object it gave +2/+2 to even if that object isn’t a creature at the beginning of the next end step.
