I feel SC's best use at the moment is as a cheaper Clone Chip for anyone relying on Clot. While it lacks the instant speed of Clone Chip, the Corp will still know to expect it and start playing around it. So why not save Clone Chip for a disposable program like Parasite, trashable or Dogbreaker, while having a SacCon in play to save that Clot?
SacCon essentially guarantees that the corp must spend two turns at least (plus any extra SC) purging if they want to FA without Psycho.
At 1 influence it can even replace / supplement Clone Chip in most Anarch decks. In Criminal it can extend the shelf life of Faerie for more facechecking, and allow you to run without fear alongside your Autoscripter.
In Clot-dependant Hayley builds it functions as a free double resource fodder AND has the same benefit mentioned in paragraph 1. And now that Power Shutdown is rising in popularity, this can also waste some Corp cards.
SacCon is looking pretty good if you ask me.
