Gatherer Card Rulings [Nov 2009]

• 10/4/2004: Can target an untapped attacking creature. Both parts of the effect will try to happen even if one part does nothing useful. So if it tries to untap an already untapped card, it will still make the creature neither deal nor receive damage.
• 10/4/2004: The creature is still part of the combat. It just has its damage prevented. Don't infer something from the fact that it becomes untapped.
