What do you have to lose by not including Jinteki cards in your HB deck? Snare! is great for RnD and HQ protection and setting up a surprise kill. Mushin No Shin can be an important fast advance card and a good bluff alongside some Cerebral Overwriter. The biggest loss here is Caprice Nisei though, and that alone might be enough to discourage the use of Custom Biotics: Engineered for Success.

So without access to these cards, what are you left with? You can still threaten the tried and true SEA Source/Midseason Replacements/Scorched Earth combo. Fast Advance play is definitely an option as you can slot in 3 copies of SanSan City Grid and still have 13 influence to spare. You can still make a great Glacier HB (although not having Caprice here will definitely hurt.)

There are definitely a lot of options that Custom Biotics: Engineered for Success opens up with so much influence to spare. And the loss of Jinteki cards isn't that impactful for the most part. So why doesn't it see play?

Simple: Why play CB when you can get the pure economic advantage inherent in Haas-Bioroid: Engineering the Future? And that's what it usually comes down to with HB. EtF still have the best built in econ in the game, and with added access to Caprice Nisei, that is why CB will almost always remain in the binder.

SURGE!!!

This card is insanely powerful and flexible in any virus wielding deck. 1 click and 0 creds for 2 virus counters? That's nuts. It's kind of crazy that it doesn't see more use. Don't believe me? Prepare to be SURGED.

Parasite taking too long to kill those pesky Tollbooths? SURGE IT! If it doesn't kill it out right, it's at least Yoggable the turn after you Parasite it. Or, just outright kill any <=3 str ice. That's value, mofo.

Playing Noiseshop and want to make insane amounts of money fast? Lay down a Cache and then SURGE IT! That's 2 clicks for 5 credits. Nearly a Queen's Gambit without the gambit!

Speaking of Noise, how about Gravedigger? One measly asset trash and you can mill 3 cards off the top of R&D! Not to mention the one you milled by installing Gravedigger.

Medium/Nerve Agent taking too long to get scary? Don't give them time to ICE up! SURGE THE SHIT OUT IT! One run and a Surge and your next run accesses 4 cards!

Sick of your Imps running dry too fast? Don't waste a Clone Chip! Just SURGE IT! Now you have double the Imp for only half the price!

Wanna slow the Corp down and force a purge? Throw down a Chakana, run R&D and then SURGE!! Watch them cry as their Astrotrains go flying off the rails.

Feeling really batshit crazy? Why don't you finally make that Deep Thought deck you always wanted and SURGIFICATE IT!!! Scope out R&D and snipe them Agendas.

Don't even get me started on Hivemind...

The worst thing you can say about Surge is that it takes up 3 deck slots. But you don't really care do you? No. You don't.

Get out there and SURGE.

With a scored Improved Tracers (new 3/1 agenda coming out soon in Data and Destiny), this ice becomes a 4 STR, 4 sub sentry with base trace strengths of 2, 3, and 4. That's a monster of an ice for 5 credits, especially in NBN: Making News. Just make sure you have an Exposé or Witness Tampering nearby to deal with the bad pub.

Since exposing is very underutilized in Netrunner, it isn't very likely that the net damage will ever land. (Unless you are playing against Silhouette: Stealth Operative, but she isn't very popular either.)

Trashing a program for a click and two credits is good value, but it's the runners choice, which severely limits the punch in the mid and late game. Also, if there is a Crypsis or Overmind on the board it is worthless.

At 3 influence, it's not even likely to be splashed, so there is no surprise factor with it being played out of faction. All in all, a very weak trap, although the flavor is fun.
