Build suggestion to farm 36/40 challenges?

Hello, I'm looking for a build suggestion that I can go to get my challenges done. Initially I planned to play something like this from league start, but I didn't resist the urge to play wintertide brand.

Is there something specific to this league (other than luminary)? I was thinking on going for WORB or ED/Contagion but I'm not sure on how Uber viable those are on SSF. I don't have a lot of gear/currency but I don't mind grinding for it as long as I can do that with the build.

Any suggestiong?
