Returning Witch with Carrion and skitterbots

Hey.

Just returning from 3.13

Due to real life I don't really have a lot of time for Leagues anymore and will dabble in Standard.

When I played Ritual I was rocking this build here, dunno where I found the build or who made it back then, but is this still somewhat viable?
