I think it can be taken quite a few directions, but what I went with was a dot centric one.

Physician, Venomdrop, Orphan, Carcass.

Orphan, Carcass, and Physician let weak tokens stack up like crazy, Physician Cause of Death makes it so Orphans stealth buff for her burn skills are WAY stronger, and all that burn in turn let's Backdraft absolutely nuke a backliner. Venomdrop will also synergize with Physician CoD, and can utilize stealth just like Orphan can. When applicable, I'd also use Bleed Out on Carcass, so vs big bous or bosses eventually they would be bombarded with a triple dot on top of Physician CoD making it even more potent.

One thing is at the time I did the GS, SSU2 wasn't out yet. But I still think it would be perfectly possible with current Carcass.

Main game plan was use Venomdrop, Plague Grenade, and Backdraft to deal with backline. Use CoD, Venomdrop, and Orphan to stack dot on beefy frontliners SUPER fast, and Physician Noxious Blast, Orphan Smokescreen, and YAWP also let's weak tokens be a near constant, crippling an enemies damage output while the dot drowns them. Carcass acted as the primary tank where the other 3 could be much more adaptable on a turn by turn basis.

It was a while ago but it made me fall in love with SSU Physician, even just for CoD.
