One ruling from Wizards of the Coast
- 24 September 2021The blocking restriction is applied only when blockers are declared. Once a creature equipped with Hedgewitch's Mask becomes blocked by a creature with power less than 4, increasing that creature's power won't cause the equipped creature to become unblocked.
