Gypsy is capable of giving off illusions. She can blend into things, making her chameleon like. She has small tp powers and limited precog. She's also a good hth fighter.
Dane is a TP/TK user with increased strength, speed, and durability thanks to the symbiote. He's also a weapons and fighter like Cable.
Ill go with the Mutants on this one. Not sure how powerful Gypsy & Sensor girl are so curious to see how they could deal with Fantomex misdirection. Also Logan & Laura's higher durability should come in handy.
Sensor Girl has the ability to see through the illusions of reality. She can also give off realistic illusions herself that even fooled the entire Justice League, including Superman (even though he eventually saw through it).
Vixen has a decent healing factor if she calls upon the right animal as does Dane.
Can anyone there stand up to Vera Black? Fantomex may be able to misdirect her, but she's pretty much above the power curve here. She even has solid protection from psychics and claws.
