So I have two questions but they basically revolve around the same principal. If Victor Mancha gets stunned but still manages to damage the opponent (say he gets stunned while attacking) then does his ability trigger? Also, if a RA character equipped with Leapfrog gets stunned does the opponent still have to mill?

Victor's triggered power is triggered off of losing endurance, which means it checks after the event to see if it could work. As he is stunned after, it wouldn't work.

The Leapfrog's triggered power is triggered off of a character becoming stunned, which means it checks the moment before to see if it could work. As the Leapfrog's ability was active in the moment before the character became stunned, it would work.

1) DCR Zazzala's power triggers even when she's the one to leave play
2) Victor's power triggers even when he's stunned while stunning someone.

502.4: A Really Confusing Rule

But Victor's power isn't a power that triggers off an object becoming stunned, leaving play, or causing breakthrough. It triggers off losing endurance.

They gotta give them something.

They only have 11 cards in the set.

Good point. That said: 11-drop Surfer's power does stay in effect when he's stunned in combat, effectively giving him Invulnerability. So I'd assume the same principle applies here.

But 11-drop Surfer doesn't have a triggered power. It works differently.
EDIT: This is why Silver Surfer works.

Well, I'm out of ideas.

What's so complicated? It just doesn't work because the trigger couldn't have worked since the character is stunned after the fact.

I think Pi is right... its not a condition from one of the exceptions.

However, it's also a trigger condition we've never seen before, so it's possible 504.2 will be updated to add it to the list, seeing how it makes sense to bunch it in with those.

Maybe, but as is, you can't assume they will change the rules for this card (especially since you'd think they would have for Qwardians, who have a trigger off of endurance loss). So, as of now, they have not stated that a trigger off of losing endurance would be a special case.

Well maybe you can activate it on the chain when the attack happens and if he stuns back that endurance lose will count.

What? What is activating? What are you referring to?
