One ruling from Wizards of the Coast
- 15 April 2013Exiling the creature card with scavenge is part of the cost of activating the scavenge ability. Once the ability is activated and the cost is paid, it’s too late to stop the ability from being activated by trying to remove the creature card from the graveyard.
