SSF deep delve build ideas

So i decided to play standard SSF for a few months to catch up on new core mechanics since i haven't played properly for a good few years now. (shaper/elder)

Decided to roll with steelmage/ziz's dd necro and clear speed in maps is great
but i was wanting something specifically for darkness/deep delve. Not really sure what to go with in SSF. Alot different when you can't MF and buy gear

Is SSF deep delving a thing? I can't imagine it given the gear requirements.
