Cerebral Static was a later include. I was playing -2CS, +1 Rainbow, +1 Crick (for a non-archives server, maximum Batty recursion!) beforehand.
To be honest it only did work for me vs a Hayley build, but that match was my only loss of the day with this deck anyway, so I guess it didn’t do enough work for its slot. There are so few real trashable things in this deck that it’s almost a dead draw against Whizzard.
I would recommend trying out Clones Are Not People for sure. I may actually snipe that idea for an upcoming GNK (unless I choose to bring a Jank deck out). It would be very thematic, considering the latest Jinteki flavours in the Mumbad Cycle.
Rainbow was originally as pure anti silverware tech, but then I started liking it just as a basic gear check (makes Cobra stronger), is reasonably expensive to get through unless they have a full rig (eg. 3 credits for Corroder), costs 2 cards to Faust (the big angle on my deck is that I play cards that tax Faust and D4V1D as much as possible), and at 4 str it is sturdy against Parasite.
If you don’t like Rainbow, I can see cutting them for something like a Crick and an Inazuma (inazuma into Cobra is amazing. Did pretty well in my testing)
