You know, this thread actually made me interested in a non-bloodlusted Nightcrawler vs Cap thread. Cap has a pretty good strength (though NC is no slouch here) and durability edge but Nightcrawler is much faster, and has a powerset would make him an absolute b*tch to tag.
Anyway, Caps team has the strongest (Spidey) and most durable (BP; They may not be able to hurt him) members but Fox has the biggest powerhouse (NTW; if she blasts anyone besides maybe BP, they're done; she is a glass cannon though) and a teleporter (Nightcrawler could just drop them from a mile up). I've run through multiple scenarios but I can't see Fox dealing with BP before someone KOs NTW. WS, Spidey, and Falcon all have ranged capabilities so someone should be able to tag her with something pretty quickly. After that, Fox's biggest threat is Cable and his insane concussion/force rifle, which he may be able to get some mileage out of before someone takes him out. Still, that rifle wouldn't take out Spidey or BP. BPs durability and NTWs lack of durability are my deciding factors. Also, anyone Spidey webs up is done. Nightcrawler wouldn't be able to teleport away since he'd be anchored and no one else can break out besides possibly Beast. On top of all that, Cap is the only tactician/leader here so he could prioritize targets and give his team the right combo of orders to steer them into the win. I'd give it to Caps team.
EDIT: Just saw this is CW BP. That suit didn't have the feats to suggest it could help him survive being dropped by Nightcrawler so a good drop would take him out. In fact, Nightcrawler could do that to anyone on the enemy team besides Spidey. Unfortunately, that wouldn't happen. NC isn't bloodlusted and he's too much of a pacifist to kill. A self imposed no-kill rule is a huge problem despite his powerset since that restricts him to punches and kicks. He would be more of a factor if he used his power set to it's full capabilities like his dad. Caps team still wins, but I wanted to correct that line about NC.
