I used white magneto pre-fight ability on mordo

Are you reviving your champs? Strength in numbers means you suffer -12.5% AAR (and attack) for each knocked out champ in your team. If you aren’t entering the fight with all your other champs alive, the AAR can prevent your parry stun and other abilities from triggering.
