Carte Magic Darksteel Mutation

Darksteel Mutation 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 Enchanted creature is an Insect artifact creature with base power and toughness 0/1 and has indestructible, and it loses all other abilities, card types, and creature types.

How it works : Darksteel Mutation

Original English text — Wizards of the Coast / Scryfall

  1. #1· Wizards of the Coast

    In some rare cases, the creature may have subtypes other than creature types before becoming enchanted with Darksteel Mutation. If it had any other artifact subtypes (such as Equipment), it will retain those. If it had any subtypes other than artifact types and creature types (such as Shrine), it won't retain those.

    No other card is named in this ruling.

  2. #2· Wizards of the Coast

    Darksteel Mutation overwrites the printed power and toughness of the enchanted creature, as well as any characteristic-defining abilities that define power and/or toughness.

    No other card is named in this ruling.

  3. #3· Wizards of the Coast

    The enchanted creature will be only an artifact and a creature, not any other card types. It will be only an Insect, not any other creature types.

    No other card is named in this ruling.

  4. #4· Wizards of the Coast

    However, Darksteel Mutation does not overwrite effects that change the enchanted creature's power or toughness without setting it to a specific value (such as the ones created by Giant Growth or Glorious Anthem). It also won't overwrite the effect of counters.

    No other card is named in this ruling.

  5. #5· Wizards of the Coast

    Darksteel Mutation doesn't affect the enchanted creature's colors, if any. It will continue to be whatever color or colors it was before Darksteel Mutation entered the battlefield.

    No other card is named in this ruling.

  6. #6· Wizards of the Coast

    The creature will keep any supertypes it previously had. Notably, if Darksteel Mutation is enchanting a legendary creature, that creature will continue to be legendary. Also, if it's enchanting a commander, that creature will continue to be a commander.

    No other card is named in this ruling.

  7. #7· Wizards of the Coast

    Darksteel Mutation causes the enchanted creature to lose all abilities except indestructible at the time it becomes enchanted. Any abilities the creature gains after that point will work normally.

    No other card is named in this ruling.

  8. #8· Wizards of the Coast

    Darksteel Mutation overwrites any previous effects that set the enchanted creature's power or toughness to a specific value. Any such effects that start to apply after Darksteel Mutation entered the battlefield will work normally.

    No other card is named in this ruling.
