Question

I have a question about enemy responses to “activating against you” such as on Infinity Gauntlet, or “attacks you” such as on Ultron I. In each case, does the response resolve if an ally defends the attack? Also, if an attack initiates against Player 1 and Player 2 defends, which player resolves the response? Thanks!

Erratum

Firstly, even if an ally defends against an attack, the villain is still considered to have attacked the player that controls that ally.
Secondly, for the cards you mentioned, what’s important to note is that both cards use the word “after” (and “Response”) to signal their timing triggers. This “after” tells us that their abilities are checking which player defended against/was targeted by the ability.
So, whichever player defended against Infinity Gauntlet’s villain’s attack or Ultron I’s attack would be the one to resolve the rest of their respective effects.
(Note, we may errata Infinity Gauntlet to specify “After attached villain activates against you” for consistency.)
