This card is perfect. Not because it is an interesting flatline counter that is cheap in the early game, but more expensive later. No.

This card is one of the most philosophically challenging pieces of science fiction published in the last decade. Think about it. Noise has created and discarded a sentient being that is physically and cognitively indistinguishable from himself. This society not only teaches people to use others as disposable tools, but also to apply that philosophy to themselves. This card teaches us that the clone has plans and dreams much like the runners we know and love: when it dies, you trash your hand of possibilities for its future.

On the other hand, perhaps the self is merely the continuation of a pattern of thought and behavior, which, though distorted by physical death, can persist in the memory of others?

"So, hear me out on this - what if, in this age of aggressive disappearances, Noise wasn't in fact the latest to go? What if, before all these missiles went through windows, and wigs got thrown into bins, Noise got taken out by his own clone? What if he knew his cruel fate to be used as a corpsoidal decoy. What if he saw it coming and said 'screw that'! What if this clone outsmarted and subdued the original, Dexter style. What if he tranq'd the punk, glued his hands to the wheel and sent him flying into the nearest wall? And what if, after a few years of keeping up appearances, that 'Noise' just had enough. The real Noise would never retire, but his clone, not wanting to be a slave to the original's lifestyle, has decided to do his own thing, and THAT'S why he's disappeared. I dunno man, it makes you think..."

"Would you just trash the damn card, already?"

(Game talk: It's a fun reset card. Probably not the best, but the idea of setting up some Data Foldings a Shadow Netand saying 'you'll never take him alive, suckers!', before clicking back a Levy AR Lab Access is still incredibly fun)

So it seems everyone is forgetting that scorched earth isn't the only way to flatline runners. It may not be ideal, but you can run into any number of advanced traps that are meant to damage and kill you, and have that NOT happen. Not getting flatlined seems better. It's not instantly tutorable like deus x is, but that is a shaper card, and not every anarch deck has the influence and it doesn't help against brain damage anyway. But they'd certainly like it if they want to see what that 6 advanced card is in weyland, or that mushin no shin just put out. The damage doesn't even have to kill you, you could just run into a cerebral overwriter, and not have to be stupid for the rest of the game. This isn't necessarily an anti scorch card, though if you're clever, you can manupulate that situation if you're playing resource denial.

This card costs the same as plascrete carapace, but it's a resource, and thus can be trashed before the scorch happens. But what if you played it with a fall guy? Then they have to trash it twice. Then if you have less than 4 cards in your hand, they can kill you. So when did you start playing netrunner exactly that you think having less than that number of cards against flatline is healthy? Adding 2 credits and a click, or 4 credits and 2 clicks on the scorched earth price tag? for only 4 meat damage?

Be warned, Freelancer is a hard counter. (Tries to roll eyes hard enough to blind himself permanently)

One more thing I'd like to highlight, as the most of it was already told by everybody that came before me - it is a very viable counter to everybody playing Midseason Replacements as it removes up to helluva lot tags, which is, coincidentally, exactly how many tags you are going to get versus your average Corpie tagstormer. It can absolutely ruin their day, which is what every runner ever should feel obliged to do, to bury the very idea of playing and winning with cheap tricks. There, I said it. You cheapskates, you.

EDIT: I have just realized that this ability can only be launched in response to damage, not to mitigate a hoard of tags all by itself. So unless you have a way to provoke damage you can prevent, you still get PsychoBeale'd. The only thing coming to mind now is Tri-maf Contact, but how do you trash it on demand? Or, perhaps, use a Street Peddler to quickly drop Titanium Ribs or Net-Ready Eyes? This seems like not much of a price to ruin somebody's game - especially if that person is a tagstormie!

Sacrificial Clone has use, although a niche one. Anarchs that seek to win on a single 'glory run' will like him as an in-faction method of damage prevention against traps. There's a few builds that basically pump up Incubator and other virus stuff, throw it all on Medium, and then dig your entire deck at once. This is obviously a risky move against Jinteki and anyone else who happens to be running traps. Sacrificial Clone is an in-faction way of surviving your last turn- as long as you can make sure it is your last turn.
