Infest

[Claymore-One]

If I played Infest on my main phase, and I played Black Knight on my 2nd main phase. Will the knight die?

If my opponent has Caller of the Claw and I played infest, will the tokens he get die?

Thanks.

611.2c. If a continuous effect generated by the resolution of a spell or ability modifies the characteristics or changes the controller of any objects, the set of objects it affects is determined when that continuous effect begins. After that point, the set won't change. (Note that this works differently than a continuous effect from a static ability.) A continuous effect generated by the resolution of a spell or ability that doesn't modify the characteristics or change the controller of any objects modifies the rules of the game, so it can affect objects that weren't affected when that 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 enter the battlefield or turn white afterward.

If a spell or ability generates an effect that modifies characteristics, the set of objects it affects is locked in when the effect begins. Infest will only affect the creatures that exist when Infest resolves.
