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?
