**418.1. A continuous effect modifies characteristics of objects, modifies control of objects, or affects players or the rules of the game, for a fixed or indefinite period. A continuous effect may be generated by the resolution of a spell or ability or by a static ability of an object. | **'''418.1.'''

**418.2. Continuous effects that modify characteristics of permanents do so simultaneously with the permanent coming into play. They don’t wait until the permanent is in play and then change it. Because such effects apply as the permanent comes into play, apply them before determining whether the permanent will cause an ability to trigger when it comes into play. | **'''418.2.'''

***418.3a A continuous effect generated by the resolution of a spell or ability lasts as long as stated by the spell or ability creating it (such as “until end of turn”). If no duration is stated, it lasts until the end of the game. | ***'''418.3a''' A continuous effect generated by the resolution of a spell or ability lasts as long as stated by the spell or ability creating it (such as “until end of turn”).

***418.3b The set of objects that are affected by continuous effects from spells, activated abilities, and triggered abilities that modify the characteristics or change the controller of those objects is determined when that continuous effect begins. After that point, the set won’t change. Note that these work differently than continuous effects from static abilities. Continuous effects that don’t modify characteristics or change the controller of objects modify the rules of the game, so they can affect objects that weren’t affected when the continuous effect began. | ***'''418.3b''' The set of objects that are affected by continuous effects from spells, activated abilities, and triggered abilities that modify the characteristics or change the controller of those objects is determined when that continuous effect begins.

Continuous effects that don’t modify characteristics or change the controller of objects modify the rules of the game, so they can affect objects that weren’t affected when the continuous effect began. | ||
'''Example''': An effect that reads “All white creatures get +1/+1 until end of turn” gives the bonus to all permanents that are white creatures when the spell or ability resolves—even if they change color later—and doesn’t affect those that come into play or turn white afterward. | ****'''Example''':<Br> An effect that reads “All white creatures get +1/+1 until end of turn” gives the bonus to all permanents that are white creatures when the spell or ability resolves—even if they change color later—and doesn’t affect those that come into play or turn white afterward. | ||
'''Example''': An effect that reads “Prevent all damage creatures would deal this turn” doesn’t modify any object’s characteristics, so it’s modifying the rules of the game. That means the effect will apply even to damage from creatures that weren’t in play when the continuous effect began. It also affects damage from permanents that become creatures later in the turn. | ****'''Example''':<br> An effect that reads “Prevent all damage creatures would deal this turn” doesn’t modify any object’s characteristics, so it’s modifying the rules of the game.

***418.3c If a resolving spell or ability that creates a continuous effect contains a variable, the value of that variable is determined only once, on resolution. See rule 413.2f. | ***'''418.3c''' If a resolving spell or ability that creates a continuous effect contains a variable, the value of that variable is determined only once, on resolution.

***418.3d Some effects from activated or triggered abilities have durations worded “as long as . . . .” If the “as long as” duration ends between the end of playing the activated ability or putting the triggered ability onto the stack and the moment when the effect would first be applied, the effect does nothing. It doesn’t start and immediately stop again, and it doesn’t last forever. | ***'''418.3d''' Some effects from activated or triggered abilities have durations worded “as long as . . . .” If the “as long as” duration ends between the end of playing the activated ability or putting the triggered ability onto the stack and the moment when the effect would first be applied, the effect does nothing.

'''Example''': A permanent with the static ability “All white creatures get +1/+1” generates an effect that continuously gives +1/+1 to each white creature in play. If a creature becomes white, it gets this bonus; a creature that stops being white loses it. A creature spell that would normally create a 1/1 white creature instead creates a 2/2 white creature. The creature doesn’t come into play as 1/1 and then change to 2/2. | ****'''Example''':<br> A permanent with the static ability “All white creatures get +1/+1” generates an effect that continuously gives +1/+1 to each white creature in play.
