Knulls Lair, Mystics and Mutants Only???

Talhamaziz

Fellows, I have gone through venom path of threat level 4 in Knulls Lair, got the mysterium but did not get the milestone rewards as seen in the screenshot.
My team was:
Dr Doom (Mystic)
Domino (Mutant)
Captain Marvel Movie (Cosmic)

I fought venom with Dr Doom.
My only mistake was that I took a cosmic in my team?? But I see players taking other than mystic and Mutants.

The objectives say Mutant and Mystic only. You’ll get the objective done for completing Knull, but not the others

Demonzfyre

You attack team has to be mutant and mystics. You have a cosmic on your team.

If other players took other champs apart from mystic and mutant then they would not get the rewards regardless
