Konjin is a really interesting piece of ice. A third of the times the runner encounters it, it is going to do absolutely nothing but force a Psi game, but two in every three encounters you'll get to have the runner encounter the most dangerous or taxing piece of ice you have rezzed. It's somewhat unreliable, but this is kind of like getting a piece of ice two thirds as good as your best ice for only 3. Definitely a good deal for any glacier deck with huge ice like Chiyashi!

There are some pretty scary ways runners can beat Konjin, though. Hunting Grounds blanks it once per turn, and Hippo can trivially trash it (breaking no subroutines means you broke all of them). I doubt Konjin will be the centrepiece of any ice suite anyway - that's more likely to be the expensive ice you're copying with it - but its worth considering its placement carefully to avoid stuff like Hippo.

Finally, Konjin makes possible a three server Mythic ice combo with Mother Goddess and Loki. With exactly these three ice rezzed, you can have two servers be impenetrable to traditional (Fracter, Decoder, Killer) breakers, and a third server secure 2/3rds of the time. Thankfully Mom is rotated now so we won't see this in Standard, and I'm not convinced its reliable enough to stand up to the crazy kinds of things runners can do in Eternal.

This is going to sound weird but I think Seidr might actually be the brain damage ID. Sorry Cybernetics Division, I have tried to love you, but its over.

What does spending/losing s mid-run have to do with brain damage? Spending s is how you turn the nasty brain damage facecheck penalty on Viktor 1.0, Heimdall 1.0 and especially Fairchild 3.0 into a gentle "miss half a turn". Seidr tips that end of the scale by also offering recursion, which is going to force some runners to take it on the noggin to keep that away from you. If you love jank you could even tip the scales back the other way again for a pretty severe catch-22.

In general a lot of lost s during runs come from ICE subroutines, so Seidr makes facechecking more dangerous. Therefore, if you rush to score out, you can force the runner to run while your ID still has teeth on those nasty facechecks, and maybe you can threaten a kill if they go too fast and end up reducing their handsize.

Even with Engineering the Future gone Seidr has stiff competition from economy IDs. Sportsmetal in particular can rush faster and keep tempo while trading agendas with the runner. But none of these are quite as cool as Seidr, and if you went out of your way to look up reviews of this ID that won't deter you from having your fun.

The Class Act has an interesting interraction with an old and hitherto virtually useless piece of Criminal hardware: Window.

When you click Window for the first draw of your turn with Class Act in play, you look at the top two cards of your stack and put one on the bottom, which you then draw. This is different to a normal click to draw with Class Act because you now know the top card of your stack!

Unfortunately the maths does not work out for combining these two cards with Oracle May. For you draw two cards and gain 2. You could have done this clicking Professional Contacts twice and saved yourself having to assemble a three card combo. On top of that, knowing the top card of your stack in Criminal is as easy as making a successful run.

Bit of a useless interraction in the end, but one that I thought was neat enough to be worth mentioning.

Once again Weyland prove themselves to be comically evil. Poor Darwin! Let our boy free!

Secure and Protect is similar to Priority Construction. Both are double operations that allow you to install ice at a substantially reduced cost. Pri Con is a pretty reasonable card, but it doesn't see that much play. Is Secure and Protect better?

Well, Secure and Protect can only install ice protecting your centrals, meaning you can't get a discount on building your deep glacier remote like you could with Pri Con. On top of that, you don't get any advancement counters on your ice, meaning you don't get to turn on the nasty Hortum or Mausolus subroutines. Looking bad for Secure and Protect.

The fact that Secure and Protect tutors for the discounted ice is both a blessing and a curse. On the upside, you can find the perfect piece of ice to match your opponent's breakers - or lack thereof if you're rigshooting. Weyland happens to have the exceptionally taxing and cheap Meru Mati and Afshar in-faction, so good news if you want to secure HQ! Downside is you reveal the ice, so you won't surprise the runner.

On the whole, this card is not particularly exciting for any existing Weyland archetypes. Perhaps Blue Sun will want to save influence on buying in multiple Chiyashi and will use this to tutor for an Oversight AI target? Or maybe the yet to be revealed Weyland ID due in Uprising - presumably SecTech - will reward you for defending your centrals?

Comparing Demolisher to the gold standard of trashing assets - Scrubber - it doesn't look all that appealing. On a single access, they both give you two extra credits with which to trash an asset, but Scrubber is half the cost to install! Is it worth paying 2 more for +1 memory? Furthermore, Demolisher competes with Turntable and Patchwork for the Anarch console slot, meaning you give up on messing up corp agenda shenanigans and converting cards into economy, respectively.

There are upsides to Demolisher, however. Unlike Scrubber, Demolisher will actually grant you a real credit the first time you trash Rashida Jaheem or NGO Front, whereas Scrubber just wastes one of its recurring credits. Also, if you access multiple trashable cards in a turn, Demolisher will reduce all of their trash costs by 1, which means you can save credits on trashing faster than with Scrubber. Finally, Demolisher will also pay you back when you trash corp cards in unconventional means - such as with Hippo, the Anarch cutlery suite, Freedom Khumalo: Crypto-Anarchist's ability, and the new Chisel.

So, does Demolisher pull ahead of Scrubber? Seems doubtful. That increased install cost is a big turn-off. Maybe if you're absolutely mad about asset trashing you'll play both, as they do compliment each other nicely. It's potentially also the console of choice for Whizzard: Master Gamer if you're playing casually and allowing rotated IDs.
