Carte Magic Metamorphic Alteration

Metamorphic Alteration is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.

01

Official card text

Enchant creature As this Aura enters, choose a creature. Enchanted creature is a copy of the chosen creature.

How it works : Metamorphic Alteration

Original English text — Wizards of the Coast / Scryfall

  1. #1· Wizards of the Coast

    You can choose only a creature on the battlefield.

    No other card is named in this ruling.

  2. #2· Wizards of the Coast

    Metamorphic Alteration copies exactly what is printed on the chosen creature (unless that creature is copying something else or is a token; see below). It doesn't copy whether that creature is tapped or untapped, whether it has any counters on it or any Auras and Equipment attached to it, or any non-copy effects that have changed its power, toughness, types, color, or so on.

    No other card is named in this ruling.

  3. #3· Wizards of the Coast

    The characteristics that will be copied are determined as Metamorphic Alteration's effect first begins to apply. If the copiable values of the chosen creature change later, or if that creature leaves the battlefield, the enchanted creature's characteristics are unaffected.

    No other card is named in this ruling.

  4. #4· Wizards of the Coast

    If the chosen creature isn't normally a creature (for example, if the chosen creature is an animated Treetop Village), the enchanted creature becomes a copy of that noncreature permanent. This causes Metamorphic Alteration to be illegally attached, and it's put into its owner's graveyard. The previously enchanted creature returns to being itself.

    No other card is named in this ruling.

  5. #5· Wizards of the Coast

    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.

    No other card is named in this ruling.

  6. #6· Wizards of the Coast

    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.

    No other card is named in this ruling.

  7. #7· Wizards of the Coast

    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.

    No other card is named in this ruling.

  8. #8· Wizards of the Coast

    If Metamorphic Alteration somehow enters the battlefield at the same time as another creature, it can't have the enchanted creature become a copy of that creature. You may choose only a creature that's already on the battlefield.

    No other card is named in this ruling.

  9. #9· Wizards of the Coast

    Metamorphic Alteration can cause a creature to become a copy of itself. This generally has no effect, but if that creature has a pair of linked abilities, the new abilities it has from the copy effect aren't linked to the abilities it had before.

    No other card is named in this ruling.

  10. #10· Wizards of the Coast

    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.

    No other card is named in this ruling.
