Question

While playing against Klaw I flip “Sweeping Swoop” (Spider-Man Nemesis #3) and “Concussive Blast” (Under Attack #4) as Boost cards during the Villain’s attack. “Sweeping Swoop” states to stun the attacked character if the activation deals damage, and “Concussive Blast” says to deal 1 damage to each character I control. The attack itself doesn’t do any damage since there’s no Boost Icon in either card and Klaw (stage I) has an ATK of zero. But does the damage from Concussive Blast qualifies nonetheless as damage dealt by the activation and should I therefore Stun the attacked character because of that? I know that a previous ruling stated that damage resulting from a Boost ability during an attack does not count as damage dealt by the attack, but does it count as damage dealt by the Activation? Is the Attack just a part of the activation or the activation itself?
