So I recognize that replacement effects are chosen in order by the affected object/player's controller per
616.1. If two or more replacement and/or prevention effects are attempting to modify the way an event affects an object or player, the affected object's controller (or its owner if it has no controller) or the affected player chooses one to apply, following the steps listed below. If two or more players have to make these choices at the same time, choices are made in APNAP order (see rule 101.4).
My question is, in the case of multiple "Next Time" effects, say, Circle of Protection activations, are all of the uses forced to happen at the same time? If a replacement effect isn't used, does it work similar to regeneration shields, in that they can still be used later?
Circle of Protection: Red has an activated ability with oracle text as follows
1: The next time a red source of your choice would deal damage to you this turn, prevent that damage.
- Adam activates Circle of Protection: Red two times during Nat's Beginning of Combat step, choosing Nat's Dragon-Style Twins (A red creature with double strike).
- Nat attacks with his Dragon-Style Twins, and Adam does not block.
Will Nat's Dragon-Style Twins deal combat damage during either the first strike or normal combat damage steps? Obviously, please cite your answer, thanks!
