Sulphurous Swamps is Terrain Strategy with Discipline.
Discipline works as follows:
Discipline: A special trait that consists of the word “Discipline” and a Gold cost icon. Players may play a card with Discipline from their own discard pile for one of its action, paying the Gold cost in the icon as an additional cost of the action, or adding the Gold cost to the action’s if it already has a Gold cost. Then, after that action ends, remove the card from the game.
Does it mean, that playing this card via Discipline only destroys a Terrain, puts this card into play, then removes it from play? (So that no Terrain is left in play?)

Discipline works as follows:
Does it mean, that playing this card via Discipline only destroys a Terrain, puts this card into play, then removes it from play? (So that no Terrain is left in play?)
Strategies with Discipline that, like Terrains, put themselves into play, are removed from the game the next time they leave play, rather than after the action ends.
The entry for "Discipline" will be updated to reflect this in the next version of the Comprehensive Rules.
