For the Corp, agenda choice comes first as you realize you absolutely must run Government Takeover; you're otherwise short 2 agenda points. Once Takeover goes in, you're 14 points shy; all three agendas have merit. You can avoid running Firmware Updates if you want to, but why would you? Most of our Ice has advancement token synergy and we will be running it. From there it's a matter of choosing if you respect Glenn Station or not. I don't. Glenn's stated purpose is to hide an agenda until you're ready to score it; a fine purpose in a deck tuned to score agendas quickly. But in this pile, protecting centrals will be an ordeal, never mind scoring a 4/2 in time to hide our Government Takeover. I pick 3 High-Risk Investments and fill out with 1 Glenn Station.
ID choice follows. We're playing 8 agendas and our only tag punishment is Traffic Accident, so Argus Security seems poor. Titan pumps Firmware Updates and High-Risk, and I wouldn't fault you for picking it. But Titan has two main strengths we can't leverage: Project Atlas and 17 influence. Gagarin gives us some omnipresent taxing, which I think will help where this deck will struggle: the early game. It's possible I'll eat my words later.
Constellation Protocol is a fine card with all our Space Ice, so we play the full 3; it's even Gagarin-approved. Mark Yale is here for the Firmware Updates combo, and any economy is desperately welcome. Space Camp gives us free advancements, which we love. The Board is utter nonsense.
Ice selection is more about choosing what NOT to play, given our limited selection; we have 24 possible ICE to run, and one of them is a unique 15-cost monster. Since we're only running 1-of Orion (that's dodgy enough) we have 22 ICE left. Asteroid Belt, Nebula and Wormhole are fine, turning on all your advancement token cards. Builder I have a strong dislike for, but we need Ice that doesn't cost 9.
Checkpoint is the Ice I like the least, and I choose to cut. As hilarious as it would be with Sub Boost (build-your-own Hadrian's Wall!) we really don't want the bad pub, I feel. Also, given it's highly porous nature, it's a poor fit against Wantonly Destructive runners.
Fire Wall is the cheapest ETR Ice we have, which says a lot about the quality of our cards. Searchlight is...well, not good, but we have all this advancement token nonsense, and the Runner plays Data Folding, so tags have value.
Accounting is strong, and turns of Protesters. I like Patch as a card, but in a world where your Ice will either be ignored or Eaten, Patch is nothing more than a 1-time 2-credit tax, if that. Not worth a card. Traffic Accident is not a card in a world without Account Siphon, and you'll never kill anyone with it given how reliant they'll be on Data Folding.
Satellite Grid is sweet and we want 3. The Twins enable cute plays, like double-Nebula to snipe an Eater, so maybe I'm wrong for cutting them, but I can't imagine they'd be relevant often enough to warrant inclusion.
Going over to the neutrals, Sub Boost is sweet. Sub Boosted Builder is suddenly a real card, as is Searchlight. It makes them easier to Eat with Cutlery, but you have more Ice than they have Cutlery.
This is 45 cards; we desperately want economy, and if you squint hard enough Dedicated Technician Team looks like economy. We'll try 3. Cyberdex Virus Suite rounds out our 49, but I wouldn't fault you for questioning that.
-The Board (Delays the inevitable)
-Checkpoint (Maybe I'm wrong, but I don't like BP and super-porous non-punishing Ice. No, it's not punishing to face-check. They can just jack out.)
-Patch (Mostly worthless in an Eater-meta)
-Traffic Accident (when is the Runner going Tagme with 3 cards in hand, none of which are IHW?)
-The Twins (My guess is you'll want to install most of your Ice, not trash it for cute plays)
