① If the effect of a DARK monster is activated on the field/GY, negate that effect.

Card Rulings

  • This doesn’t stop monster effects from activating. It just negates any effect which does activate (on the field/GY).

  • Even if the Physical card is no longer on the field/GY, the effect is still negated. If the monster is face-down when its effect resolves, the effect is still negated

Card Text

When the effect of a DARK monster activates on the field or in the Graveyard, negate it.

Card Rulings

  • When determining if a monster’s effect should be negated by “Shadow-Imprisoning Mirror”, check the monster’s Attribute at the time its effect is resolved.

  • When a Non-DARK monster’s effect is activated while the monster and “Shadow-Imprisoning Mirror” are both face-up on the field, if you chain “DNA Transplant” and select “DARK”, the monster’s effect will be negated if the monster is still face-up on the field when its effect resolves because it is now a DARK monster.

  • “Shadow-Imprisoning Mirror” cannot negate Unclassified or Continuous Effects of DARK monsters.
