I'm convinced that this card is extremely strong in Shaper, given the current Corp meta. Shapers do not have a good answer to the current mix of HB Foodcoats ice in particular, which is usually some mix of Ichi, Assassin and Vikram. Atman 4 makes you vulnerable to the latter two, Atman 5 to the first, so Atman is not a good solution. Cyberdex makes Datasucker support problematic.

However, all three of these are tracers, all are broken by Gingerbread for the same cost or less as the rez cost (which is a fair measure of whether a breaker is efficient).

It also backs up your Lady against NBN match-ups, meaning you can use Lady for Wraparound and Gingerbread for Resistor. 5 credits for Archangel seems bad, but that's the same cost as Gordian. 5 credits for Gutenberg is also bad (given that paying off the trace is 7), but if you're click starved rather than money starved (a common scenario) then paying 5 to avoid the tag and keep your clicks is better than paying 7. However, if you add in NRE then suddenly Gingerbread is one of the best breakers in the game for dealing with Archangel and Gutenberg. It's also as efficient as Mimic at breaking Caduceus.

Given that Yellow and Purple are the dominant corps right now, tracers are everywhere. Gingerbread deserves a second look to fill out your Shaper breaker suite. I have not been disappointed with it.

While I agree with most of this, where is your math on mimic and caduceus? Mimic takes 2 to get through caduceus, whereas gingerbread takes 4, 2 to boost, 2 to break. —
With NRE, sorry. Should have made that clearer. —

You only need enough credits in Netrunner to win - any more is a waste of clicks or cards. For that reason, generally it's only worth killing connections that stand to make the runner enough money from now until the end of the game that would enable them to win. For instance, if they've recently installed Kati Jones and have started loading her with cash, she's a good target. Once they've emptied her, she's less appealing, since there's a myriad of ways they could leverage that cash to win the game. However, if they then spend that cash on a few runs and don't win, suddenly she's an inviting target again. Similarly with Professional Contacts, if the runner is sitting on 30 credits then there's little difference between drawing or ProCoing, as they're unlikely to use all that cash by games-end.

It follows then that the best time to kill key connections is when the runner is poor and rig-building. So my question is, why would you spend 4 money and 4 clicks on Contract Killer to kill the runner's connections, when you could spend 1 or 2 clicks and maybe a few credits to Snatch and Grab the connection instead? Yes, it's hard to Snatch and Grab Kati Jones if she's just been unloaded, but that's also the worst time to use Contract Killer on her since she's fulfilled her purpose. The meat damage ability is not very worthwhile, since 2 damage is only enough to kill if backed up by Scorched Earth; at that point you may as well just play Midseasons and Traffic Accident.

It works quite well as runner bait - if they run your server then you have taxed them through your Ice. If the eave the Contract Killer alone then you have killed a connection for 4 credits rather than for as much as they were willing to spend on defending that connection, especially if they have a credit lead. It also turns on SEA source/alternative tag source , 2 Meat damage, 4 meat damage which can be more of a surprise than Midseasons Traffic Scorch. —
GRNDL Refinery and actual traps work much better as runner bait if that's your aim. If your aim is to win by meat damage, then you're better off running Shattered Remains to deal with Plascretes. As I pointed out, the argument that sometimes it's going to cheaper to play Contract Killer than Snatch and Grab is spurious because its generally a waste of 4 clicks and 4 money to kill a Kati Jones if the runner is rich enough to defend a Snatch and Grab. The setup required for factoring Contact Killer into a flatline play as compared to double scorch or Traffic/Scorch is huge. Too many things have to go right, and I think playing this card over those if you want to threaten a flatline is a mistake. —
It isn't that it is better than Snatch & Grab, or at particular traps at any ONE thing - the argument for this card's use and effectiveness is that it suits a variety of roles to suit your purposes. Snatch & Grab is useless if they have no connections, traps are no good if the Runner can expose them, Traffic accident is only good if you can land a multitude of tags. Sure, they all do their ONE thing better, but Contract Killer isn't just trying to be just one thing. Also, as an aside, there are plenty of in game situations where the runner has a lot of money, with more on Kati. Runners are getting very rich in places at the moment. —
I think it's important to note that contact killer can't be countered, only mitigated. Yes, there are other card combos that are quicker and more brutal but you either need multiple cards or require a trace to land in order to use them. If the runner has ways of beating traces, or dropping tags, they can avoid loosing a connection or taking damage at a crucial moment. They don't even need to be way a head, 3-4 creds is all it takes in some cases. When you use Contract, they don't have those options. —
With Old Hollywood out, Kati isn't even the only connection worth killing anymore. Film Critic stops a lot of Weyland kill methods. —

Turing is a necessary addition to the game, completing the trinity of AI-hate cards along with Wraparound and Swordsman. When facing lots of Turings in their meta, anyone running Darwin, Crypsis, Overmind or Eater only decks will either have to bite the bullet and switch to a full breaker suite, or else find ways to capitalise on making runs that use up their whole turn.

Aside from that rather hefty boon, I see a number of distinct problems with Turing that make it my least favourite of the new "technological revolutionary" ice that were released with Breaker Bay.

  1. If it's not protecting a remote server, Turing is weak to Parasite. Unlike Swordsman, where you get the huge advantage of knocking out a key program mid run, functionally Turing is just going to act as a hard stop for AI-only decks. Not coincidentally, these decks are almost universally Anarch decks, which also pack Parasite. Wraparound is naturally resistant to Parasite absent a fracter, but Turing on a central is 2 turns away from death (less if they're using Datasuckers). If you're trying to find ways to slow down Eater+Keyhole, Eater+Account Siphon or Eater+Vamp, this is not the card for you.

  2. Alright, so it needs to go on a remote server. Except outside of Replicating Perfection, we know full well that cards like Eli 1.0 are unreliable as the runner can always just click through if they really want to get into the server. Turing faces a similar problem. Absent some additional tricks like Ash 2X3ZB9CY or Caprice Nisei, Turing is merely a nice taxing card, but tax isn't good enough if your intention is to score all your agendas via a well-defended remote.

  3. Alright, so let's put in Ash 2X3ZB9CY and Caprice Nisei, since they're good cards anyway! What's Turing doing for us then? Well, not a bunch, to be honest. 4 for 5 strength and 1 subroutine is a middling cost-to-tax ratio, and is going to be eaten alive by some of the more common code gate breakers like Cyber-Cypher. It compares unfavourably to a lot of alternative HB code gates like NEXT Bronze, which is cheaper and has a higher tax-ceiling in combination with its siblings, and Viktor 2.0 which at least has a couple of subroutines to add to the tax. Mostly, you'll be spending 4 credits to tax the runner by about 4 credits per run. If you're looking to set up a well-defended remote that depends on tax to create scoring windows, you can probably afford the much more effective Tollbooth.

  4. At 3 influence, it's unlikely to be imported to any other decks, which means Jinteki, Weyland and NBN will have to make do with Wraparound and Swordsman to deal with AI-heavy metas.

So yeah, if you're playing HB and can't afford the influence on Wraparound or Swordsman this might be a useful card for you. Otherwise, I feel HB is a little spoiled for choice in terms of decent, mid-range code gates.

I don't like to count bioroid code gates as reliable for the same reason as eli, except worse because viktor 1.0 can just give you brain damage as you pass him by for a click, and viktor 2.0 —
whoops, anyway, viktor 2.0 takes 2 clicks, and one of his subroutines is more or less useless most of the time, so it's 1 more credit for a slightly more expensive, yet unreliable code gate —
wow, I really don't mean to be hitting enter...need an edit comment function. So the point is, the code gate situation isn't amazing in hb, I would say nbn has the best code gates, and as far as mid range would go, I'd rather rez a yagura then viktor except in certain builds. Gyri Labyrinth, hudson, hourglass are all very limited options, where turing can certainly stop eater/anything for a crucial turn. And it's a bonus if you can force a cyber cipher on a remote, doesn't have to be your scoring remote, and it's a decent tax for most other decoders. Next Bronze wants you to use more next, so it's not a universal option. I agree that the influence is high, but having 3 of these in RP would probably be silly. —
It's excellent for protecting a non-agenda remote like Adonis, Eve, SanSan, or Haas Arcology AI to make the runner spend their whole turn trashing it. —
@cmcadvanced, There are 3 things Viktor 2.0 has that Turing doesn't. If a Runner hits a Turing with not enough clicks and no decoder, it's a hard stop. If they hit a Viktor with not enough clicks and no decoder, it's a hard stop and a 1+2 credit tax (or, if the corp is rich enough, a brain damage which is always nice). 2. It's more taxing in the long run, thanks to the two subs. I'll pay 1 credit more now for an extra 1 credit tax every time the runner runs through it. Good trade. 3. You probably don't want to see Turing in your opening hand because it seems a waste to go on a remote. Ice that is self-limiting in that way is a hard sell given the precarious nature of most HB early games. Viktor, on the other hand, is very good on any central and will do in a pinch on a remote to try and force an asset through. —
It improves the "clicking hell" deck, and of course synergises well with several HB upgrades such as strongbox, heinlein grid and rurhr valley. And its probably worth the influence to play one or two in RP. —
Is this considered an "end the run" subroutine? Does Endless Hunger work on it? —
Endless Hunger should not, as it specifically says "End the run." subroutine, this sub has different text than that is targeting. —
So I assume the runner actually has to have 3 clicks to lose? —
Yes —
