Jinteki's stock definitely seems to be going up.
I like the new identity, but I forsee it being hard to manage well. If you can somehow maintain your three central servers, with a Tollbooth installed at the outermost spot on each, it might be pretty useful. Even better if you can get an Archer on each, but that would be way too difficult for Jinteki. Otherwise, the most you're likely to get out of it is a wasted action each round, and maybe a credit or two, before the runner can run your agenda server. Even then, the runner may be able to make use of the run so that the action isn't even a waste, so it's hard to say how well this identity will work.
Again, though, I feel like FFG has undermined the new identity before it is even released by putting it with a card that promotes the use of the core set itentity. Fetal AI pairs so well with Personal Evolution that it almost feels like an exclusive agenda for just that one identity. 3 damage for stealing an agenda (and 2 credits out) is pretty huge. Now the runner has to run with a full (or Dieseled-up) hand when running to score, or they'll be hurting big time. When Trace Amount hits, I'll probably start running Net Shield more often, just because the damage is going to start adding up… unless something better comes along for dealing with net damage.
Trick of Light is also a card I can see myself splashing in quite a few decks, but it's definitely good that they made it a Jinteki card. Jinteki really needed something like this. They are supposed to be the trap masters, and yet I feel like they are currently the worst corporation right now, especially with pulling off the traps successfully. This will help to make their traps more versatile, and may even cause the runner to consider running an advanced junebug, knowing full well what it is, just to trash it.
