I fought a duped Emma Frost with Magneto HOX and I couldn't evade her specials. You know how her specials are reversed when duped. I later found out he's immune to reverse control so I should have dodged it like it was any other defender. I wasn't sure where it said in his abilities, but someone pointed out a description in his tags...pic below.

Now, Prof X also has the same tag on top and clearly stated ability in his description of his immunity to reverse control...pic below.

I took my Mags HOX into Act 6.4.4 [Cap Marvel Movie Boss], tried is on the lane with "Special Chaos Inversion" node and he wasn't immune. However, I saw a video of Prof X immune to "Delirium" node. See pic of node on 6.4.4 below

Any idea on what's going on? Is it working fine or there's a bug (known or unknown)?
