One ruling from Wizards of the Coast
- 18 April 2017If the creature's power is greater than 2 as the activated ability tries to resolve, the ability won't resolve and none of its effects will happen. However, if instead the creature's power is raised above 2 after the ability resolves, it still can't be blocked that turn.
