General Rulings - 417

• 417.1 - A one-shot effect does something just once and doesn't have a duration. Examples include damage dealing, destruction of permanents, and moving objects between zones. [CompRules 2003/07/01]
• 417.2 - Some one-shot effects instruct a player to do something later in the game (usually at a specific time) rather than when they resolve. This kind of effect actually creates a new ability that waits to be triggered. (See Rule 404.4.) [CompRules 2003/07/01]
