Armed Asset Protection is an “archived card types matter” transaction.

Best case, you can net +$8, from $2 to $10 (= -$2+$3+5×$1+$2). For example, if you've resolved another operation, gotten an asset trashed, installed over a rezzed piece of ice, gotten an upgrade flipped faceup from an early archives breach (that you'd discarded to max hand size), and expended an unstolen agenda.

Worst case, when Archives is empty (or completely facedown), it's worse than just clicking for a credit (+$1). nb. Operations are “nonbasic actions”, and can't get any worse than “playing it is worse than taking some basic action” (unless it were stealable, I guess.)

When the three “safe & easy” types to trash (ie. operations, assets, upgrades) are archived faceup, you net +$4, like a Sure Gamble.

Note also that you can expend three card types (which are trashed faceup):

1. ICE (Tree Line)
2. Upgrade (Angelique Garza Correa)
3. Agenda (Slash and Burn Agriculture)

Compare:

• Extract: Also a thematic transaction (Weyland’s theme in Borealis Cycle being “sacrificing installations”). nb. AAP synergizes with trashing rezzed cards too.
• Government Subsidy: AAP can have a greater profit margin with a lower initial investment (or… lesser profit with higher investment than even Beanstalk Royalties).

• Blockchain: Another “archived matters” Weyland earner, interestingly.

Oppo Research is a “pseudo-reprisal” terminal multi-tagger.

It has two modes:

• a cheaper/earlier-game, but weaker, mode: 2 tags for $2; and
• a stronger, but pricier/later-game, mode: 4 tags for $7 (and threat level 3).

For example, if they steal a single 5/3 on even their first turn, then you can quadruple-tag them on your second turn, because both the play-requirement and the threat-gate get satisfied (unless they forfeited it, or bankrupted you, or so on).

The play-requirement is looser than “they stole” (eg. Distributed Tracing) or “they trashed” (eg. Threat Assessment), but tighter than “they succeeded” (eg. Public Trail) or “they ran” (ie. HNN).

Compare:

• Hard-Hitting News, the “older Oppo”.
• Midseason Replacements, the “oldest Oppo”.

Flavor: Opposition research is an organization (the Corp) collecting "biographical, legal, criminal, medical, educational, or financial" information on an individual (the Runner) to discredit them.

Fujii Asset Retrieval is both protective and proactive: it does 2 net damage whether either player steals/scores it (just as it raises the threat level by 3 in either score area).

Design: I really like such agendas (ie. with When this agenda is scored or stolen, … triggers or … This ability is active even while this agenda is in the Runner's score area. statics).

Compare:

• Sting! (or ½ Obokata Protocol + Philotic Entanglement): damaging Jinteki agendas.
• SDS Drone Deployment and Bellona: offensive–defensive 5/3’s.

Note that, because it has a conditional ability and not an additional cost (as @Diogene says), FAR:

• can poison Archives if trashed (like two Shock!’s); but
• cannot defend itself if the Runner already has 4–6 agenda points, even if they only have 0–1 cards gripped (eince the game ended as soon as it was stolen, before the stolen-trigger could resolves).

Synergies:

• in Jinteki: Personal Evolution decks, FAR reads When this agenda is scored or stolen, do 3 net damage..
• Neurospike or Punitive Counterstrike: Its trigger contributes 2 points of damage and its agenda point value another 3 points of damage.
• AP (and damage defense): Agendas that protect themselves via damage amplify ice/upgrades that also protect servers via damage. eg. behind a Daniela Jorge Inácio, and an Attini or Saisentan, Fujii is quasi-unstealable. (cf. Ikawah Project with bioroids.)

Flavor: The "assets" are clones and the "retrieval" is re-enslavement.

Oracle Thinktank both punishes stealing (by tagging) and can negate stealing (by shuffling itself back).

Compare: TGTBT, crossed with 15 Minutes or Quantum Predictive Model.

Note that the Corp can only steal it right back on their next turn if: the Runner doesn't untag (unlike 15 Minutes), didn't already have 6 agenda points (unlike Quantum Predictive Model), et cetera.

Note also that you don't have to cash the tag in for the -1 agenda point (you can just keep it around for some tag-gates, or spend it on another tag-cost).

PS. A “purple Oracle Thinktank” (Haas Thinktank?) could do a core damage to be stolen and heal a core damage to unsteal itself:

As an additional cost to steal this agenda, the Runner must suffer 1 core damage.

[click], remove 1 core damage token: Shuffle this agenda into R&D. The Corp can use this ability only if this agenda is in the Runner's score area.

Ablative Barrier is an early-game gearcheck and late-game non-agenda installer/unarchiver.

Design:

• Threat-gated “when rezzed” effects, like Threat-gated operations, play differently than Threat-gated repeatable/continuous abilities (Jaguarundi’s “when encountered”, Vovô Ozetti’s static abilities, and so on). This means that by the mid-game, when choosing whether to rez or even install Ablative, you'll be weighing “now” against “more”.

• Install 1 card from HQ or Archives is narrowed with non-agenda and in the root of or protecting another server. This keeps the rez cost (and threat level) low, and lets you play more with (still broad) subsets of a (super broad) effect, to weave a distinct texture.

For example, you can bring back the (self-trashing and easily-trashable) Rashida Jaheem (which, against a run-last-click, reads When you rez this ice, draw 3 cards and gain $3.!); but you cannot sneak in a Project Vitruvius, nor can you ice up the current server with a Magnet.

Compare:

• Drafter and Ansel 1.0.
• Echo, Tatu-Bola, and Ping.

(Tatu-Bola being Jinteki's 1↳-and-1s-for-$2 ETR ice with some “post-ETR” value.)

By the way, any gearcheck can (implicitly) act like a Pulse trigger, since they waste the click spent on that run (by ending it), which synergizes with click-taxing (in HB esp.).

When you rez this ice during a run 
against this server, the Runner loses [click].

Flavor: In Pathfinder, an "ablative barrier" is a spell that blocks things and pushes them away.

Invisible layers of solid force surround and protect the target, granting that target a +2 armor bonus to AC. Additionally, the first 5 points of lethal damage the target takes from each attack are converted into nonlethal damage.
