Kinda swamped with work right now (and trying to make a Comet Tacos deck work… damn you @Zeromus for putting that idea into my head!), so I haven’t playtested it too much. Here’s what I’ve come to so far:
3 credits strikes me as too expensive for what it does. You don’t save slots on combo pieces (still need at least Scavenge, ideally also Test Run) and probably need to run 3 copies, at which point Sahasrara basically becomes superior, as far as pseudo-econ for Prof goes.
You can see the problem as soon as you start considering the quintessential “power-turn program”: Sneakdoor Beta. With the Library, you pay 3 and have a resource out to be able to save 4 credits for 3 Sneakdoor runs. With Sahasrara, you pay 1 MU to get a 2-cred discount on pretty much each of your installs from then on until forever, and can Scavenge it into something else that’s been binned (like, a free Parasite, Faerie, D4V1D - whatever’s needed, really). Not being able to host virii (which are, like, half of every Professor deck I’ve ever built) is the final nail for me right now.
The big problem with this kind of deck, however, is that if you meet someone playing Blacklist, you’re just done. And as El-Ad wrote on Twitter last week, if your netrunner deck folds to a single card, you have a problem 
Shame that Career Fair is not a green card (or that Prof doesn’t have, like, 5 influence), otherwise it’d be very kickass in a Prof build, empowering London Library, Daily Casts and Professional Contacts. As it is, I’d be paying 3 credits for:
- A free turn of Keyholing
- A free turn of Sneakdooring
- Using Femme like a weird Inside Job (potentially repeatable, at the cost of 3 clicks total)
- D4v1d-related OAI Curtain Wall nukeage
Now… those are extremely potent cases if you notice, but they’re also kinda narrow. Could be worth it as a one-of, potential trick (if you’re running Escher in your Prof deck, for instance, this could go in that slot), but it’s not a full-fledged econ engine (which is the thing he desperately needs). For it to become so, it needs more programs out that are all of:
- Expensive
- Not a virus
- Best used in a power turn (think like Sneakdoor or Keyhole)
-
(bonus) Out of faction for Shaper (to avoid the goddamn “Kate does it better™” problem
)
So… fingers crossed that this cycle has some of that?
p.s. if the hosted program didn’t count against your MU (it’s on the Library computers anyway, right?), it would become much more interesting - letting you get good uses out of things like the afforementioned Keyhole/Sneakdoor or a SMC with your memory full. I don’t think it does that, though - no mention of such a feature on the card text.
