Alright, first I know that bringing up how ANB works is a sore subject, so I apologize for that
First, I just want to make sure that
the ruling that ANB is inherently CBI stands with the new SI rules. As it removes all characters from the battle, it creates a losing condition. However, in order for it to complete, the ability sends the game to a new phase. Is the ruling still going to be that it nothing can stop it after it is played through de facto CBI?
Second, this brings up the question about Herods:
Herod Agrippa II 6/6 Acts 25:23 Gold E Negate protect abilities on Fortresses. If a Hero withdraws from battle, you may capture it. May band to a Sadducee. Cannot be negated. [Jewish King] War
Herod's Treachery - Matthew 2:8 Multi EE Place on a Herod. That Herod may use evil Enhancements regardless of brigade. You may discard this card to force X Heroes to withdraw from battle. [X=number of good brigades opponent has in play, territory class] N
If an ability returns all heroes to territory while Agrippa II is out (this is one example, there are others), then in order for it to finish AII will capture them (because they withdrew). This capture is CBN. Is the rescuing player able to interrupt/negate the source of withdrawal, or are they just plain captured?
