3 rulings from Wizards of the Coast
- 4 October 2004Count the number of creatures on resolution of the spell and divide X by that number at that time. If the number of creatures changes before resolution, the damage done may be different than what you expected.
- 16 September 2007For example, if X is 5 and the targeted opponent controls three creatures, Dwarven Catapult deals 1 damage to each of those creatures.
- 1 February 2014If the targeted opponent controls more than X creatures, no damage will be dealt to any of them.
