One ruling from Wizards of the Coast
- 29 June 2026Desert Were-Worm's second ability will only trigger if creatures you attacked with had power 12 or greater at the time you attacked. Increases to the power of attacking creatures after they attack, such as from attack triggers, will not contribute to the 12 power needed for this ability to trigger.
