Something not touched on in the other reviews is how a 2/1 in purple helps fire HB's "When an agenda is scored" IDs, Precision Design and Sportsmetal.

In Precision Design this agenda is 3 & 2 to recur a card from archives and score 1 point. That's pretty good - in rush decks that want to recur combo pieces like Biotic Labor, this is slower and more expensive than an Archived Memories, but keeps pressure on the runner by increasing the corp's score and is generally quite tempo-positive. It is worth considering that whatever you just recurred from archives is open to being Imp'd from your hand before you get a chance to actually use it (unlike a 1st- Archived Memories) - but this is a minor drawback and combo decks that are already running Archived Memories would likely benefit from the additional recursion.

In a Sportsmetal rush deck, this is arguably even better. 3 & 2 for 1 point and 2 cards is akin to a bite-size version of the huge tempo boost offered by the ubiquitous Offworld Office, largely reinvesting the clicks spent scoring the card out. If you were planning to spend 2 drawing cards already (something that rush decks might do when assembling combo pieces) this now equates to ",2: gain 1 point" in Sports. Sports also already want to run lots of 1-point-or-less agendas as food for cards like Fast Break, Giordano Memorial Field and the late Game Changer, so this is right at home.

Of course, these effects are nothing new - they apply to any agenda played in the above Identities... but the possibility of being able to score Élivágar Bifurcation from hand with no combo pieces or setup required makes these effects a lot more reliable... barring any blocked datafeeds. I can see this becoming an auto-include in PD and Sports decks of the future.

I think this card is very shrewd. Derezzing doesn't create a lot of value, and this card is priced accordingly. Bifurcation is a 2/1 agenda very playable even if you don't plan on using the derez effect. In contrast, a card like Hakarl is completely unplayable unless you value derez effects highly.

If you were going to print HB's first 2/1 agenda this is probably the best way to test the waters. A blank 2/1 will probably be better than a low-impact 3/1 like Hyperloop Extension, and those are either currently (or at least recently) tournament-viable in Sportsmetal.

(If an operation was printed for derezzing a single card, I think a $0 card "Derez an installed card and gain $2" is fairly priced).

Why are 2/1's good?

• They can let you play a deck full of 5/3's and still have a clean path to 7 points.
• The 2/1's are a lot harder to steal because you can score them from hand without any special tricks. So this is attractive to Glacier-type decks.

In Weyland this is a common pattern for corps on SDS Drone Deployment. Their plan is usually to score one Hostile Takeover and jam SDS.

A difference though is, Haas Bioroid already has a lot of access to fast advance tools -- it's not like they couldn't easily score 1 point from hand if they really wanted to before. But, maybe they can use the Biotic Labor and Bass CH1R180G4 slots in some other way now.

Why is this 2/1 good?

There were a lot of comments on Hákarl 1.0 about how to use the derez effect profitably:

• De-rezing Spin Doctor means you can re-rez it for free and instantly draw two cards. A lot of decks have spin doctor. So now compare the effect of scoring this agenda to scoring Superconducting Hub.
• De-rezing Marilyn Campaign or Nico Campaign means that you can re-rez it for free and put more counters on it. So now it will keep giving you money for longer. This won't actually give you any benefit until a few turns from now, and if the runner trashes that card then there's no benefit. But at least this may be profitable at some point, or pressure the runner to actually go trash it.
• De-rezing Anemone means you get to re-rez it and do two net damage again. However, you can't rez it a second time unless the runner runs it, so this isn't going to accomplish much except grinding the runner down a bit. (Anemone isn't super interesting in Haas-Bioroid, it was more like, maybe a Jinteki deck would import Hákarl 1.0.)
• De-rezing Hákarl 1.0 means you get to re-rez it again and trigger it's on-rez effect again. However, this isn't likely to have any impact. The point of that effect is to make the brain damage stick if they face-check the ice, but if you are de-rezing it then they already know what it is.

Those comments considered the midnight sun booster pack. But in the full midnight sun, there are a few other interactions worth noting:

• De-rezing Trieste Model Bioroids means you can re-target it when you re-rez it. This might be useful if e.g. the runner put Femme Fatale on the ice it was targetting.
• De-rezing Wave means that when you re-rez it, you can trigger every rezzed copy of Echo to add another subroutine. That potentially gives you a way to beef up all your echos and make them really annoying. (However, that may be bit janky, because Anarchs will still break them pretty cheaply with Buzzsaw or destroy them instantly with Chisel.)

Overall, the de-rez effect seems pretty marginal.

The way I imagine this agenda being useful is something like:

• A MirrorMorph: Endless Iteration deck that runs pretty rich
• Agenda suite is 2x Élivágar Bifurcation, 3x Project Vacheron, 3x Send a Message
• Game plan is, score one Élivágar Bifurcation, then jam Vacherons in a scoring remote repeatedly until eventually you score one of them, then score another three pointer for the win with Big Deal on the next turn. (Maybe using Digital Rights Management here to go faster, or even Malapert Data Vault to tutor the Big Deal).

The Élivágar Bifurcation is helpful because, even if they steal both, the runner steal needs to steal at least two 3 pointers to win. And you don't need to pack Biotic Labor or spend money on Biotic Labor, you can use those slots for Big Deal instead.

Think of the Magnet value! Or maybe other ice that has an on-rez effect. Otherwise just neat to see de-rez getting some focus. And as far as 2/1 agendas go there are certainly ones with more downsides.
