Something where powers like probability manipulation, Gambit stuff, marksmanship, and invisibility would come in handy...

How about an accident at some Photonic Energy Lab? Requiring a two-man team to get in and navigate the photon fields (would invisibility render someone immune to light-based damage? I've honestly never considered that before.) to shut down the generators powering everything before the out-of-control energy pulses annihilate everything in an X-mile radius? And, of course, pulling injured personnel out of the rubble of the collapsing facility and making new exits?
