This card is exactly what Weyland needed. A thug ith a baseball bat smashing the runner's fingers saying, "No!" after they trash your Multibillion credit mining industry. Seriously, this card is great. Punishment has always been a concept trodden lightly upon, but never really explored. We got Hellion Beta Test in Flashpoint, which was a good start, but I think this card is even better.
Pros:
costs a mere 1 credit to use
Does not rely on tags or other prerequisites other than a trashed card, which is very easy to arrange
Does not give Bad Publicity or require a successful trace like Hellion Beta Test
Can cause a chain reaction effect if used to destroy memory giving consoles. Additionally, many runners throw away their extra copies after they've found one, this could make that a painful mistake
Multiple copies can utterly destroy a runner's boardstate. Taking the hit from one copy leaves the open for punishment by another
Cons
Removes itself from the game, but I doubt you'd need to recur it
Nullified by Sacrificial Construct
4 meat damage seems like a huge setback, but some runners would rather take the hit and can even benefit them if they are running I've Had Worse or Clan Vengeance
Overall I think this is an excellently designed card that will find its way into many Weyland decks running high-priority assets or upgrades
