I started drooling when I saw Kill Switch, then cried when I noted the influence cost.
I’m not surprised Kill Switch didn’t excite anyone else, because very few people play the Jinteki kill deck like I do. In my deck, landing any amount of brain damage makes your kill shot that much easier.
The idea that I can boost the 3 trace to 5 really cheaply makes for a painful choice, especially when stealing an Obokata against PE. Pay 5 credits and 5 cards? Or (supposing they won’t die) 6 cards including a brain? Pay nothing, eat the brain damage but leave Obokata? Pay 5 to avoid the brain but leave the Obokata?
These are all great for me at the low cost of 2 credits for those nasty choices (3 if you include the current cost). That extra input from me is flexible based on my game state, and can make for extra punishment when I go for a kill shot.
Downsides for me are the high influence cost, and that a Runner current clears it. I have some room to juggle so I will probably make space for two and see what happens.
Not a tool for most people, but I see its potential.
