I played an Aetherborn tribal deck a few months ago, and the plan I felt that was super strong involved Yahenni, Undying Partisan and Syndicate Trafficker. They can both survive Bontu's Last Reckoning with indestructibility and then it becomes a blowout. Yahenni getting 3 or 4 counters after wiping the opponent's board. Also, sacrificing an artifact to Syndicate Trafficker can be useful with cards like Servo Schematic. I believe there are some cards you could cut a few copies of--i.e. Tezzeret the Schemer, maybe could be a 3-of--and some you could cut altogether--i.e. Weaponcraft Enthusiast is pretty awful and Panharmonicon doesn't seem to do enough in your deck.
I played Mono Black Aetherborn quite a bit before the latest rotation. The bolded is spot on for an Aetherborn tribal and is the engine for it IMO. It had bad match ups of course. It did fairly well at around a 60% overall win ratio. If they allowed my board to develop it could get nuts.
Below was the last iteration of the Mono Black. It my help as a reference. Ob Nixilis Reignited was the last addition for a card draw and secondary creature removal. The local meta I was playing in was heavy with Plainswalkers and Gods. I'm playing a UB Improvise since the rotation.
With a UB version I would probably start with the core engine and go from there. 22-23 lands, Kingpin, Rebuke, Blue card draw, and a couple Tezzeret's Touch just to be an ass for a surprise attack

However, the cards that fed the engine were Weaponcraft Enthusiast and Servo Schematic.
