I've had a lot of success with this archetype. I've taken it to ~10+ tournaments and it has lost 3 games in total (in a tournament setting, more in testing/octgn). It is one of the few runner decks where the corp is more worried about you than you are about them, and the only runner deck I've seen lock out a game at 0 points. The object of the deck is to set the opponent to 0 credits with nothing rezzed, at which point lamprey and keyhole end the game in short order. All that being said, I stopped playing it after Blue Sun's release due to a bad matchup against blue sun glacier and architect powered hb decks (too much money to consistently fight). However with the release of O&C, I was able to free up card slots for tech against these matchups, and get it a little more powerful overall, so I no longer have reservations about playing the deck due to matchups.

2 clone chips can be a test run and hades shard should you feel the need, personally I prefer more recursion/slightly stronger parasites.
How to play: Don't let them rez R&D ice unless you're sure you can kill it. HQ ice is less important, although you will want it derezzed/parasited eventually. Keeping remote ice unrezzed can help you snipe agendas with vamp, but sometimes it's a better play to force them to rez it to make them spend money. Econ assets are must kill unless it costs you more to get in than the asset will give (namely temporary assets like adonis). Pressure HQ with lamprey, derez anything you can't parasite, then vamp for the win, keyhole ends the game but it's best used when the corp is already out of the game, eater does allow you some keyhole pressure compared to the old crypsis builds, which is good to keep in mind
This rig will let you get through most things for less than it costs the corp to rez. Yes, you can't break a swordsman, just parasite it. I got hit with 3 swordsmen at tulsa's store championship and it didn't really slow my progress much, you can vamp through a swordsman if it comes down to it.
3x Clone Chip
These do a lot of the heavy lifting. Crescentus is all 3 silverware as far as you're concerned, and it gets recurred by clone chip. Lamprey against a corp that can't keep hq ice rezzed forces a purge, usually for a 1 cost program that already got value.
The combo pieces, set them to nothing and then keyhole at no cost.
These are both metagame tech, against blue sun and asset spam decks respectively. They tend to always be somewhat relevant in other matchups, but if those decks aren't in your metagame feel free to change them for other silver bullets. Yes, I know I listed david twice, it fits in both categories.
Logos has two main upsides: it allows you to find both your matchup specific silver bullets, and combo pieces should they not be necessary, and, the added handsize helps with the combo deck problem of dead hand slots until you're ready to go off. Xanadu is actually pretty strong when they constantly have to rebuy their ice, also makes it so that the corp needs a 1 cost ice to protect hq when on 0 credits
3x Sure Gamble
3x Daily Casts
3x Earthrise Hotel
I tried to stick with slower, higher powered econ cards. You don't need much recurring money, you really just want to pull ahead of the corp for long enough to lock them out. Day job isn't in because it doesn't play well with kati, IHW isn't in because you have a good matchup against kill decks already, and earthrise is better for pure click efficiency.
Try it out, tell me what you think. Just be warned that it really isn't fun to play against.
