The copiable values granted by Metamorphic Alteration are locked in as the creature is chosen. The enchanted creature won't change if the chosen creature's copiable values change.

If the chosen creature is a token, Metamorphic Alteration copies the original characteristics of that token as stated by the effect that put the token onto the battlefield. The enchanted creature doesn't become a token in this case.

If the chosen creature is copying something else (for example, if the chosen creature is enchanted by another Metamorphic Alteration), then the enchanted creature becomes a copy of whatever the chosen creature copied.

The enchanted creature will be a copy of the chosen creature as it dies, so any "when this creature dies" abilities it gains from the copy effect will trigger. Any "when this creature dies" abilities it normally has will not trigger.
