Benjen Stark has the following text:
Interrupt: When Benjen Stark is killed, gain 2 power for your faction. Then, shuffle him into your deck instead of placing him in your dead pile.
Here's the scenario:
NW player is at 13 power - 11 is on the faction card and 2 is on Benjen. NW player loses a military challenge and has to satisfy claim.
Can he choose Benjen to satisfy the claim, and trigger his Interrupt to win the game? Based on my understanding, the Interrupt occurs before the triggering condition, so the power is claimed before Benjen leaves play. My opponent argued that the wording "When Benjen Stark is killed" would imply that Benjen is killed at the same time that the 2 power is claimed, meaning the total never changes as I gain 2 power on my faction as I lose 2 on Benjen.
Which is the correct interpretation?
