MWW / PBM / EGL ... I tag between them constantly and use EGL to eat up a super if necessary. When the bars fill up I use her sword slice, PBM's second ability, or a super from PBM or EGL. I have easily smoked teams 300,000 and under...lost one and won one with teams over 300,000.

Defensive SM / PST / ASM ... my PST is high on defense and both Supermen boost defense a lot. I start out using silver SM to build up combo meter and then use PST to do a special 2 ir 3 for tag in. I rarely bring in ASM since he's pretty useless (I have 4/5 of his armor set so that nerfs his utility pretty badly). I can take out teams that top out at 150,000 with this.

My third worthwhile team is SFF / GA / SBC ... start out by backing away with Flash to reach the corner and then I rush forward and combo, rush, combo, rush and usually take out the next guy that comes in after the first one tags out (45+ hits built up at this point), with a special 1 or 2. Occasionally SBC will pop in for the extra hits and a scream but she is the worst. I use Green Lantern to eat a special.

Those are my top team. Currently working on EPI / Bane / Batman focusing on critical hits. It's good but the team is low threat, about 45,000. But it gets critical hits every other hit so should be good once I level up the silvers.
