One ruling from Wizards of the Coast
- 24 November 2014If 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 the creature’s power is raised above 2 after the ability resolves, it will still have haste and can’t be blocked that turn.
