they were competing for dominion over the other contestants. I guess that would mean being able to use their resources. I don't think that we ever found out why Trevor Fitzroy hated Emma Frost. it's weird that he never mentioned to anyone that he's part of the Shaw line, either.
I LOVED the revamped Gamemaster in the Marjorie Liu X-23 run.
My vote was for Selene, given I don't really consider Magneto to be a villain.
I also left Magneto out, so I voted Reverend Stryke as well as I could have voted Senator Kelly. I find (in general) common humans with social/political/religious authority and influence much more interesting than bombastic people with floating impossible capes. While the last ones use to practice evil for the sake of evil, the first ones understand so well the power and profit of fear. So, I feel the need to say: "Don't let them cheat you with villains like something out of an operetta --these are the real enemy".
