I suspect if you had Torch or Archangel you wouldn't be asking for help ๐I actually found the most effective option to be using DefensiveAbility Accuracy Reduction, to avoid triggering his Neutralise. You can solo him with a champion like Falcon, Black Widow or Daredevil HK.Also, familiarise yourself with his his Ruptures work:Once he's at ten Mystic charges, he'll start inflicting Ruptures; and actually the damage stacks up a lot. Your can avoid it by (1) knocking him down to reduce his Mystic charge count, (2) avoid using Light attacks, or (3) waiting out his timer after suffering the first Rupture.Hope that helps.
