418.3b. Continuous effects from spells, activated abilities, and triggered abilities that modify the characteristics or change the controller of one or more objects don't affect objects that weren't affected when the continuous effect began. 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. 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: 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.	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.
