General Rulings - 610

• 610.1 - A one-shot effect does something just once and doesn't have a duration. Examples include dealing damage, destroying a permanent, putting a token onto the battlefield, and moving an object from one zone to another. [CompRules 2009/10/01]
• 610.2 - Some one-shot effects create a delayed triggered ability, which instructs a player to do something later in the game (usually at a specific time) rather than as the spell or ability that's creating the one-shot effect resolves. See Rule 603.7. [CompRules 2009/10/01]
