Great line-uo, only thing I would add is Hepzibah because a love relationship is always needed in a team, even though Warpath and Hepzibah seem kind of an odd pair but that's the magic of a relationship... But otherwise GREAT list!!!
Wunderbar! Very femme fatale-ish. We Psylocke, Sage, and Lady Mastermind are great, and Warpath seems rather unappreciated where I'm from. I don't know Trance or Shatterstar, and very little of Madrox, but I could stand to learn some.
Throw in Gambit. Because I like him (Kidding, it's your list. I joke to take worry or tension off).
I always love when people make a mutant team and add mutants I never heard off "Trance". Because i love checking out what what kind of power they have.
This entire team seems like Killing would happen on a frequent basis. while that is okay at some point it will start eating away at the team like in X-force. but interesting team none the less.
