Feitan is one of the worst users you can choose, like kkck said. His nen ability relies solely on "paying back" the damage he receives from his opponents. The problem is he will not survive that hit from Meryem. And let's keep it real, he's not faster than Meryem either. Meryem is simply way out of leagues for any human Nen user. The closest person who actually stand a chance is Super Gon, but that still doesn't warrant a defeat simply because we have never seen Meryem TRY at all, he's just too strong.
Meryem 1.0 will own any team or combination of Nen users, not to mention Meryem 2.0.
My best 5 is below but they don't stand a chance either, just doing it for fun:
1. Netero - his kanon fists to keep Meryem busy
2. Chrollo - his teleportation trick to move Meryem/teammates around and avoid getting hit.
3. Chameleon - invisibility to launch Potclean with Knuckle
4. Knuckle for potclean
5. Super Gon - use all of his aura (like Netero's Zero) and do one single hit on Meryem when Meryem finally runs out of aura.
or alternatively
6. Kurapica - Judgement Chain to restrict Meryem's movements or whatever, but there's a fallacy in this because Nen users can "bend the rule", not break it. i.e. - you can create a very sharp blade, but NOT a blade that cuts through anything.
Knov's ability is very useful but seeing how dysfunctional he became just by seeing RG's aura, he's definitely not fit for battle with the King.
All in all, no one can dodge Meryem's attacks; no one can deal fatal attacks on Meryem; and no one can survive Meryem's attacks. My team here only buys time, they will get annihilated eventually.
Meryem said it himself:
"I am the King that has been entrusted with the lives of all species; you are a human, not a King."
