I got 1st place at a 14 player Game Night Kit event in Madison, WI with Geist (interesting!) and NEH Team Sponsorship (boring!).

There's a much longer explanation at the original list, so I'll just go over the few changes and talk about some cards not included.

Changes

-1 Faerie +1 Shiv is basically because in most cases, Shiv is the better card. Faerie has game against Archer which is very important, but the most common sentries you'll be breaking are Caduceus, Architect and Ichi these days, and all of those are well within Shiv's effective range and Shiv gets you a bonus card for your trouble.

-1 Cerberus Rex, +1 Passport was to make sure that I had an un-drainable decoder for HQ. My previous version was pretty weak to stacked code gates over HQ since it would drain my tokens really fast and if I couldn't find enough Crowbars to get in, I'd be suffering. Passport means that as long as I've got money (and if I can get into HQ I'll tend to have it) I can keep getting in.

-1 Plascrete +1 Same Old Thing is because I found I didn't need both plascretes to survive the murder matchups as long as I was careful, and extra Same Old Things are more Siphons which are the bread and butter of the deck.

-1 Legwork +1 HQ Interface is probably the most borderline change. HQI is more expensive and slower than Legwork, which is definitely a downer in the deck. On the plus side, it works with Street Peddler, doesn't tax Same Old Thing and, most usefully, it provides a good backup to Siphon if they manage to spend all your money before you get in. It also increases your baseline pressure against HQ which is valuable for forcing ICE rezzes when you want to pressure RnD or a remote instead.

Other Cards

I tried out Fisk Investment Seminar because I thought it would be awesome for the deck, given the amount of money denial you employ. However, it turned out that if you didn't play it at exactly the right time, speeding up the corp when you're trying to lock them down is really bad. If I put a card in the deck that's going to be tough to play effectively, I want its upside to be a lot better than Fisk Investment Seminar.

I also tried several builds that put Dyson into the deck, including Sneakdoor Beta builds, Medium builds and even a Parasite build and I didn't like any of them. The late game is definitely better if you can install power cards like Sneakdoor or Medium, but what ultimately gets cut to make room for them is money cards like Security Testing. Simultaneously making the deck poorer and more expensive is tough pressure to put on this deck's early game, which is probably the most crucial phase (since if you can get a Siphon in successfully early, you're in really good shape).

I don't like Fall Guy in this build either, since its efficiency doesn't reach the level of any of the cards I'd replace it with. Some people have have enjoyed swapping the Sure Gambles for Fall Guys, but I'd rather have the extra 2 credits than the card early. The same goes for every other card in the deck as it currently is; they're all giving me a better baseline return than 2 credits and a card (Shiv, Spike and Crowbar are often giving me at least that much in savings, plus letting me into servers and Dirty Laundry is often 3 credits and a run I would have made anyway, so I could just use the spare click saved from that run to draw a card and I still end up ahead of Fall Guy).

One card I almost pull every time I edit the deck is Levy AR Lab Access, but I think it should stay in for now. It mitigates variance by giving you a way to recycle your pressure if the agendas manage to avoid you long enough for you to deck yourself. Most games you should win before you Levy, but if for some reason you don't, Levy lets you lock in a win that would have otherwise escaped you.

Let me know if you've got any suggestions! I'm particularly looking for a card to cut to allow me to play a 3rd Crescentus, as that card is just golden and the earlier you see it, the better.
