Nasty Nas don't Need No Nexus

This deck started out as a fairly standard Security Nexus build, but after some tweaking I decided to go all-in with Faust and ditch the Nexus completely. The result is a hyper-aggressive Shaper, which is a bit odd but pretty fun to play.

The Cards

Use Diesel, Astrolabe, and Game Day to draw like mad. Put down as many Public Sympathy as possible, burn through your cards with Faust, play Game Day, repeat. Hit a Levy AR Lab Access when the deck starts looking thin. Faust is absolutely essential, use Self-modifying Code to grab it.

Because you're milling through cards rapidly and playing 1 or 2 Levys per game, you're gonna have a lot of opportunities to Clone Chip. Kill weak ice with Parasite (you don't have Mimic, so you rely on Para for weak sentries), or keep popping Imp back out. Save a Clone Chip for Clot against fast advance.

Inti is only there to counter Wraparound, just feed it to Faust unless you're playing against NEB.

Magnum Opus is your only econ, but face check unrezzed ice with Nasir's ability to get extra creds. Sharpshooter and Deus X provide some extra protection for this if you don't have the cards for Faust.

Akamatsu Mem Chip you generally want to feed to Faust the first time through, but you might need it the second time around, depending on your opponent (e.g. if you need Clot and Inti on the board).

Don't hesitate to ditch good cards, just be careful with your Levy AR Lab Access and you'll get them back. Generally you want to put down your Same Old Thing as soon as you get it for Levy insurance.

Film Critic, Scrubber, and The Maker's Eye are just doin their usual thing. Escher gives you a single card to leverage the fact that you'll probably be ignoring HQ for most of the game.

Oh, and in case you haven't played Nasir: when you need to run with creds in the pool, use Personal Workshop (or Study Guide) to ditch creds before you lose them.

Basic Strategy

Hammer R&D early and often. Use personal workshop and creds from Nasir's ability to install R&D interfaces quickly. Because you mill through the deck repeatedly, you should be able to play The Maker's Eye several times per game, giving you lots of R&D access. Imp means you can use this to disrupt the corp's plans as well as to score.

Try to use Scrubber and Imp to keep the corp econ under control. The corp will try to build a big ice wall in front of R&D. Make them break the bank to afford it, take their credits, then bust it down with Parasite and/or Escher and keep on accessing. Hit R&D with enough 4-card or 5-card accesses and the game will end regardless of what archetype your opponent is playing.

For kill decks you could add a Plascrete Carapace, but I prefer to play it like a man and run naked, using Public Sympathy to keep my hand at 8+ cards whenever I think the corp has the money to kill. The best defense can be a good offense in this case--try to get a lot of early multi-card R&D accesses, trash kill cards with Imp, and score quickly. Because you're a Shaper, your opponent may not anticipate the aggression.

This deck doesn't care about HB brain damage, and against Jinteki you just have to be careful.

I mostly ignore scoring from advanced remotes and just hammer R&D, removing the temptation of traps entirely. But sometimes you have to run a scoring server (e.g. to kill a caprice on R&D by forcing a caprice rez in a remote, or because your opponent is threatening to end the game). Using Escher to open up a scoring server works well. It's generally a good idea to hit unrezzed/unadvanced remotes whenever possible, both for asset hate and to avoid this deck's arch-nemesis, Chronos Project.

I typically don't run HQ at all. Hopefully this gives the corp player the sense that you're uninterested and they leave it wide open for Escher. One exception is against NBN, where you may want to hit HQ with Imp if you suspect the corp is stockpiling kill cards.

Variations

There's a lot to play around with here.

If you want to have less fun but improve your staying power, remove 3x Astrolabe, 1x Akamatsu Mem Chip, 1x Study Guide, 1x Imp and add 1x Security Nexus, 3x Dyson Mem Chip, 1x ZU.13 Key Master, 1x Hyperdriver.

If you want to play around with influence, you could lose the Imp in favor of Utopia Shard and Nerve Agent, allowing you to hit HQ with a little more force. Or lose the Parasite and add a Mimic and one of the above.

Net Celebrity works well with Nasir. A single copy gives you the ability to cancel the corp's current and helps with asset hate. Of course, the more fun way to cancel the corp's current is to play The Maker's Eye with 3 R&D interface installed.

Don't add Sure Gamble or Plascrete Carapace though. Those cards are for losers.
