I like the good team and I'll tell you why: It's balanced. You don't have one big guy who you rely on too much.
I think you should rethink your bad team. Lose Magneto, and use Elektra, and Tessa and Scourge and Spymaster. Maybe Taskmaster and a guy with TK to round it out. I think you'll be better off like that. Magneto's just too many point for a game like this.
1. Outwit might be a problem, but with resistance the problem is less.
2. I don't have Kang. :P I could use the E Annihillus but that would mean a new team-theme. Any thoughs who would thematically team up with him?
Remember, this is scenario play, not cut-throath tournament play. :P
Hmm I think perhaps R Destiny and a 4 point Pog might be in order.
Against any team with much upfront outwit I can play the BFC Resistance, (Two adjacent models with the same team symbol cannot be targeted by outwit) and just carry Tessa with Magneto, and he's safe against outwit. And dishing out 6 damage to boot. That should kill of most supporters and dent even the thoughest opposistion.
Why not try out U Mr.Sinister or Black King? You can round out more characters with any of these. Mr. Sinister could have Vertigo, Skullbuster, Harpoon, and others. The same can be done with BlackKing. Selene, Donald Pierce, and some Hellfire members would truly screw those X-men. BFC? I feel that Darkness may be in order.
