Pick My Next Build PSC

So far this league I have done Mathil's void battery BV build (without void battery) and Angry AA's juggernaut lab runner. I prefer builds with full guides. I would really like something that is good at scaling gear and eventually being able to kill uber atziri. I have my super fast map clearer in my blade vortex, and my tanky lab runner, now I am looking for the boss killer. It looks like a lot of people are killing uber with bladefall mines but I haven't seen a good guide for it. What would you guys recommend?
