Question

If Mutant Protectors does first make your identity the defender, we’re wondering if you can play other cards that trigger when your hero defends during that brief window before your ally is declared the defender? Example: The villain attacks me. If I play Mutant Protectors, is there a window where I can play Never Back Down at any point during the resolution of the villain’s attack and my defense?
