My mostly-complainy gut reactions:
Mad Dash: This is an interesting idea. It seems like it's going to sit in your grip more often than not, though.
Signal Jamming: This would have been phenomenal from the release of C&C through the first MWL. It's still got its uses, but in a world where Shapers are underplayed and CC/Parasite isn't running rampant, I'm not sure it's worth the slot.
Network Exchange: It is really weird to me that this is out of Shaper. This is an interesting effect, though. Might find some play if Mopus/Vamp decks make a comeback? Or maybe Reina decks (lol) are spending influence on this to pair with Xanadu?
Pushing the Envelope: I kind of love this card, but I don't really know what kind of deck it fits into.
Maw: Cool. Probably overcosted, but cool.
Spot the Prey: Definitely overcosted, but interesting. Also, have I mentioned lately how much many of Damon's card names annoy me?
Bio-Modeled Network: I guess this is the (bad) replacement for Deus X. Probably necessary to have something like this in the pool. Mostly useless against the current net damage flavors, but good to have around in case something spikier comes back into vogue.
NEXT Wave 2: Cool idea to give NEXT some heft. At a 4/2, though, this is headed for binder fodder/janktown. If they had waited until rotation kicked in, I think this easily could have been printed as a 3/2 (I understand not wanting HB to have access to 3 sets of 3/2s at a time, though).
Defense Construct: Garbage. You'd think the designers would have learned by now (after all the stumbles on advanceable ice) that advancement counters are a precious resource. Reverse the rez/trash cost and it's still pretty awful, but at least it might find some space in strange new twists on IG or CI or something. As it is, though: just hot garbage, even in a post-Jackson world.
Net Analytics: More garbage. It costs a lot to force a tag onto the runner (with good reason, considering it opens up insta-kills and Closed Accounts and....), and drawing a card is poor compensation. If you're slotting this with the expectation that it's going to fire on a regular basis, you are planning on losing.
SYNC BRE: I understand the rules confusion, but there's no way this lasts until end of game. This is an interesting option for a beefier Sentry, but outside of Making News (time for a comeback!) that second trace looks a bit anemic.
Quarantine System: Uh, what? I guess this would be an interesting answer to Blackmail/DDoS style shenanigans if EBC didn't already exist. The best case is you forfeit a 2/1 -- you still spent 3 clicks and 2 credits installing and advancing that agenda, and now you get a refund of 3 credits, so... yay? Edit: forgot about the new Weyland ID. So this sets up an interesting way to more consistently FA out bigger agendas by saccing smaller ones. It's a bit combo-wombo-ey and you're mostly treading water as far as agenda points go -- but this could let you actually make use of the more powerful 5/3 abilities. Interesting.
Khondi Plaza: Not bad, but this reads to me like an overcorrection for Mumbai Temple -- rez cost could probably be lower and it doesn't need the unique restriction.
