Notes and Rules Information for Damping Engine:
  • A player affected by this card can sacrifice a permanent any time they could cast an instant. This is a special action that doesn’t use the stack and can’t be responded to. (2008-08-01)
  • A player can only sacrifice a permanent to end this effect if they have more permanents than any other player, and they haven’t already sacrificed a permanent to end the effect this turn. The ability to sacrifice a creature is granted by the same effect that is being ended. (2008-08-01)
