One ruling from Wizards of the Coast
- 1 October 2009Scute Mob’s ability has an “intervening ‘if’ clause.” That means (1) the ability won’t trigger at all unless you control five or more lands as your upkeep starts, and (2) the ability will do nothing if you control fewer than five lands by the time it resolves.
