在你的维持开始时，在疫病闷锅上放置一个疫病指示物。
：在疫病闷锅上放置一个疫病指示物，或从疫病闷锅上移去一个疫病指示物。
当疫病闷锅上有三个或更多疫病指示物时，将它牺牲。 若你如此作，则消灭所有非地的永久物。

Rulings:

• 10/1/2005 You choose whether to add or remove a counter when the second ability resolves. You can’t choose to remove a counter if there isn’t one there.
• 10/1/2005 If the third ability triggers, removing a counter in response won’t stop the effect. However, somehow removing Plague Boiler from the battlefield in response would stop the effect because then you wouldn’t be able to sacrifice Plague Boiler.
• 10/1/2005 The sacrifice is done on resolution of the triggered ability.
