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.

Example Scenario:

  1. 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).
  2. 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!

    Nat really shouldn't be attacking on Adam's turn, it's quite rude.

  • Adam had to have priority when he activated his CoP!

    @Skyl3lazer The convention of naming characters based on active player and non-active player is based on whose turn it is in the described situation. The NAP will still receive priority (just not first) and be able to activate CoP.

The Dragon-Style Twins will not deal damage in either combat damage step.

One of the subrules of the rule you quoted, 616.1e, says

Once the chosen effect has been applied, this process is repeated (taking into account only replacement or prevention effects that would now be applicable) until there are no more left to apply.

So, in the first combat damage step, the process of applying replacement and prevention effects goes like this:

  1. We start with two instances of "the next time Dragon-Style Twins would deal damage to you this turn, prevent that damage".
  2. The effect to be modified is "Dragon-Style Twins deals 3 damage to you".
  3. You choose (arbitrarily) to apply the first prevention effect.
  4. The new effect is "Nothing happens". Now there are no applicable replacement or prevention effects, so the process ends.
  5. One instance of the Circle of Protection: Red effect was applied, and the other was not, so now we have one remaining Circle of Protection: Red effect to apply.

In other words, a replacement or prevention effect that applies to "the next time" something would happen is only consumed if it is actually applied to an event.

  • I can accept this justification as "since nothing told the second effect to stop waiting for damage to replace, it persists until it finds damage to replace" Thanks!

Since the Comprehensive Rule you quoted (616.1) is hard to understand, we can use a ruling on a similar card, Dazzling Reflection, to demonstrate the intent:

If two Dazzling Reflections targeting the same creature have resolved in the same turn, only one prevention effect will apply the next time it would deal damage. The other effect will apply if the creature would deal damage a second time later that turn.

We conclude from this ruling that if two prevention effects are competing, then one will apply "next time" and the second will apply the time after that.

  • Basically what happens is you have two effects trying to modify the same event, so you choose one of them to apply (616.1d). You then check if any other replacement effects apply (616.1e), since there aren't you are done applying replacement effects. Since only one of the two effects was used the other one is still waiting to apply the next time the source deals damage.

    @diego That makes sense to me now - thanks for explaining it. I edited the answer to say "hard to understand" instead of "unclear".
