Question

If I have two X-Men allies and two copies of Mutant Protectors in hand, the resources to play both Mutant Protectors, and the villain attacks, can I play both Mutant Protectors during the same Interrupt window? Normally, once a character has been declared the defender, I don’t believe you could play a defense event or otherwise have another character become to defender. But since Mutant Protectors is already an exception to these rules, I was wondering how it would interact here.

Answer

We are ruling that yes, this is possible, but not necessarily because Mutant Protectors is “an exception.”
We have ruled in the past that it’s possible to play defense events while an ally you control is defending an attack so long as any triggering conditions are met, the most common situation being to block overkill damage with a card like Side Step. Playing a defense event for this reason would not make the player the defender, though; the defending ally is still considered the defender.
These rulings in mind, we believe that it is possible to play two Mutant Protectors as an interrupt to an enemy initiating an attack, and both allies would enter play exhausted, but only the first ally can be “declared defender of the attack.”
