Just looking at the options, presuming some cheeze / low effort battle, undying promise looks like the most likely candidate.

One mob that reraises 4 times, nothing to crowd control, no adds, etc. Says its 6 participants, but the battlefield page says its 3. I'm inclined to believe its 3 as well, based on the patterns (each area has a trio and fullPT battle).

May also be a good easy candidate based on the page descriptor. Doesnt seem like the detector attacks, only the dolls do, and only one can be up at a time.
I'm not sure if pup overdrive cheese is viable for any though, dont think OD will last long enough.
