If that were the case, then the haris and duo skills on Patsy, in Varuna, would be utterly useless. So Miranda is allowed to form a duo with any unit who can make duo fireteam in the first place.
She can’t form a link with just anyone. They have to be a valid team or wildcard. Yes a Wildcard can replace the ABH. That means only Valerya and Sforza. Also is it worth the argument that they can’t? First hardly anyone will do that and second, it’s not a game changer grouping. She can also Wildcard into anything with a Duo fire team and replace the one with the Duo Skill. There must always be at least one with that skill.
You are right, I forgot the Rafiq remote has a duo option allowing you to replace that in the Maggie's fire team
I’ve done an ABH with the Rafiq and it’s not bad. You can have a 12pt ABH that takes the lead and might sacrifice itself so the Rafiq can move into a good position. But it’s not overpowering or anything at all. I’m looking forward to trying out the Maggy though I don’t think i’ll Duo it with anything. I might keep a Liberto near it just to keep away anything getting too close.
