3 rulings from Wizards of the Coast
  1. 15 August 2010The ability cares about lands with the land type Swamp, not necessarily lands named Swamp.
  2. 15 August 2010This ability counts the number of Swamps controlled by Quag Sickness’s controller, not the enchanted creature’s controller (in case they’re different players).
  3. 15 August 2010This bonus is not fixed; it changes as the number of Swamps you control changes.
