I really like how balanced this card is.
On one hand, it's scary how it can fire from anywhere, and either of the options, (core damage or -1 point) is very impactful. On the other hand though, it can only ever fire once. This isn't like Shock! or Breached Dome of the past, that just would sit in archives, taxing the runner every time they checked it. This one fires once, but then it's gone forever, either way. And while both options are impactful, the runner gets to choose which one they want, which means it will always be whichever one hurts the runner less at that moment.
I think that the biggest strength of this card is how right now, there are no legal runner cards that let you sacrifice agendas, in either startup or standard. Artist Colony, Data Dealer, etc, have all rotated. I'm not sure if that's an intentional direction by NSG, or if they're just coming later. But historically, there have been ways to sacrifice agendas, which work nicely as a counter to things like this. Here's to hoping we see a new one soon!
If you accidentally ambushed an archive of the worst nightmares and traumas harvested from a colony of climate refugees, I imagine it would either decrease your opposition to the Corp or else do some serious damage.— StaticSky
