Part one of Big Game's game plan is to brown-nose Electron so she'll be more open to cooperation with his game plan.
Part two of Big Game's game plan is KILL THE FLASH!
Part three is to rig an innocent damsel to explode and use her as a collateral/safety net to force Professor Psychic to a drinking contest.
Part four is... I dunno, kill the Professor since his mind powers would be impaired, probably.
Part five is to interrogate the hell out of Damselfly, because if she was hired under such secretive/questionable circumstances, then she's obviously hiding something important.
We would definitely need to keep the other guys busy when dealing with PESP and Damselfly, though. Luckily Ben can handle pretty much anything Sixgun and Night Terror have to offer, although the Man of Steel, Mecha Man and the Indestructible Jew would be tough to handle. Saint Frank has a plan for the Man of Steel, though, Electron might be able to get the suit to short-circuit and Ginny might be able to get the internal computers to screw up somehow. I'm sure Succubus can get the Golden Armor guy to do something that ain't chivalric. I haven't found any great counters or targets for the others yet, but I'm sure it'll be fine if we can get our hands on enough apache helicopters.
Perhaps we should take the ladders off one of thos 30-foot-deep swimming pools, get Magarac in there, and freeze it somehow until we're ready to deal with him. Then we should root out all the human normies and have the murder tanks like Dragonfly and Crow come in and kill them while we hold off everyone else. Again, apache helicopters are key.
IT IS VERY IMPORTANT THAT IF WE GET IRON MAN TO SCREW UP, WE HAVE TO KILL HIM IMMEDIATELY! Genius/Engineer-type heroes always fix their shit afterward, and you can never defeat them the same way twice. If we don't take him out with the first few plans, we might run out of workable plans.
Actually, scratch killing the flash, Durga sounds like a natural leader/morale paladin-type hero, so we may need to use Redline's ego and power hunger to disrupt their harmony, assuming he doesn't prove to be too much of a problem for us. That way, we're more likely to get them apart and be able to take them down like a real villain coalition...
Which does beg the question as to why we shouldn't just subtly turn them against each other, but I guess uncovering that kind of scheme is Stand-Up Guy's biggest threat. Obviously we must kill Stand-Up guy so as to create a subject of blame and internal conflict as well as destroying their best detective...
