PoE Cobra Lash builds

Completely new to both Shadow and Poison. Can someone help me with this build? Playing standard.

I had an idea of abusing Nightblade with Perfect agony, so I did a bit of PoB (the real game as someone call it), and got some nice results. This is offcourse not a full build, so the 2c budget might be a bit misleading, but the point is that the items that will get this build going will cost you that much (Bino's and Ungil's) Some maths about elusive and nightblade: We have 200% elusive from nightblade and ascendancy.

With the changes to cobra lash, i decided to try something i had never done before : a poison build. I made a quick PoB of what it would look like : I did not complete the skill setup yet, there are still 10 gem slot remaining (4-link and weapon/ shield link) maybe some other skill that can be better at bossing can be used as a 6-link and cobra lash as a 4-link idk. also for the gear, i used the bare minimum for damage calculation since starter gear will look like shit, so i only have wasp nest and coralito. I'm planning to have
