Surprise!... A Blue Flower!..?

This card is for the trash! No literally it's not a bad card, far from it, unlike Snare! and other Ambush cards Shock!'s ability remains active even when accessed in Archives so it can actually be used to effectively make Archives a very nasty place for the runner to visit.

Combos

Trash it: 3 copies of Shock! in archives can land 3 net damage onto the runner when Archives is accessed. 1-3 copies of Shi.Kyū could threaten even more forcing the runner to eat negative agenda points rather than take the flatline. Did the runner score some agendas? Jinteki: Personal Evolution would could make a flatline event even more likely.

Flatline with assist from ice: With 3 copies of Shock! in archives some net-damage inducing ice like Komainu, Neural Katana etc protecting Archives may open up a flat-line opportunity. Certainly use a House of Knives token if available! (Not quite flat-lined? Perhaps finish the runner off with a couple Neural EMP when corps turn rolls around)

Uncooperative runner?: Got a runner with a light grip and archives all setup for the kill? Bait the runner with an agenda in a remote server then put Susanoo-No-Mikoto on the server (particularly if the corp sees the runner only has Mimic or no killer able to handle a heavy sentry) If the runner doesn't go for the bait, keep advancing agendas!

Quickly fill archives: Using Jackson Howard the corp can quickly mill through R&D increasing the likelyhood of finding Shock! & Shi.Kyū etc with the express purpose of discarding them. Meanwhile using operations and other cards that Jackson Howard is bringing into HQ to full effect. Not fast enough?: Power Shutdown can really trash cards from R&D in a hurry (probably will want to think about having 1 point agendas-only, really nice trick if the corp can have The Board installed when runner accesses Archives to mitigate all those one-pointers!, very likely game over if the corp is able to follow-up by scoring Philotic Entanglement.
Haarpsichord Studios: Entertainment Unleashed could certainly work here too slowing the runner's scoring ability down while each time while at the same time possibly opening a flatline opportunity every time the runner runs on Archives.

Intolerable Cruelty: With 3x copies of Shock! in archives, The Future Perfect could be a fun agenda to bait the runner with, again accopanyied with a House of Knives token or followed up with Neural EMP could make for a game ending scenario that the runner may be tempted to gambit multiple times if the psi-game fails

Showing a little leg: with Celebrity Gift for can actually serve multiple objectives if all the corp shows are Shock!, Snare! etc heavily discouraging the runner for going after any agendas that the corp didn't show in addition to the .

Advance: Even though Shock! isn't advance-able, cards like Tennin Institute: The Secrets Within Mushin No Shin can give the runner the appearance that it's an agenda goading the runner to waste time and resources only to pickup a net damage.

Protect Assets & Upgrades: Since Shock! is most powerful when 3 copies of it are in Archives, in combo with Industrial Genomics: Growing Solutions gives the corp a bonus for doing what it already wants to do in discarding Shock! thereby helping to make Ash 2X3ZB9CY, Caprice Nisei ect a little more costly to .

(Did I miss something obvious, I'd appreciate suggestions in the comments below, I may add it to this review)

Pros

Archive Poison: Active even when in Archives may negate the need for corp to even expend resources to protect Archives. Better yet possibly can open up a flatline opportunity.

Trashing Tax: Unlike Snare! and other ambush cards Shock!'s costs 2 to as opposed to 0, this is particularly helpful if accessed while in R&D or HQ

Catch 22 If runner does trash Shock! it ends up in archives which is where the corp may have wanted to put it anyway.

Cheap: unlike Snare! for example, for 0 at the corp can fire for Shock!'s 1 net damage even when broke

Cons

Weak by itself: As an asset Shock! is rather mild at only 1 net damage and no tags etc

Limited Bluffing: Since Shock! is not advance-able it can be difficult to bluff the runner into running onto it as an asset

Summary

Shock! is right at home with Jinteki at two influence point and needing 3 copies to be maximally effective in Archives it's rarely seen out of faction. Still with it's ability to poison Archives it stands out even among other Archive active cards such as Shi.Kyū, Cyberdex Virus Suite etc particularly in when it comes to dealing out the net-damage hurt.

--It just saddens me when I see cards with no reviews. If you appreciated this review, please give a heart and I'll be encouraged to write more.
