One ruling from Wizards of the Coast
- 18 February 2022Aerial Surveyor's triggered ability has an intervening "if" clause. That means (1) the ability won't trigger at all unless the defending player controls more lands than you, and (2) the ability will do nothing if you control at least as many lands as the defending player by the time it resolves.
