Chains of Command Necro league start

Hey guys, I'm planning to league start chains of command Necro since I really enjoy the build (at high investments) it felt absolutely dogshit to play at lower investments and I genuinely hated it, no idea what to farm after and some of my blight maps brick even with tower setups. I tried following Rusei's guide but couldn't make it work. If anyone has any pointers for league starting it I'd appreciate it.

Last league I played pRAW and switched when I had about 500d, pretty smooth but got bored real quick. I'd like to just play a single build in the coming league and invest all my currency into it (which is what I did with pRAW insanely fun prior to playing chains)
