The Loop Mk I

Corporation deck submitted by Bierfuizl


Paradox, Inc.: "We do anything anytime."


The text in the General Tactics and Some Tips sections is an old article of mine that I posted to the Netrunner mailing list in December 1996. As far as I know this was the first working version of an infinity loop for Netrunner. In the meantime several other variants of the 'loop' (as I like to call this kind of deck) have been built.
Wyatt Cheng developed an efficient version that is based on Team Restructurings and uses Project Consultants to score the initial agenda.
Daniel Schneider built several other variants and introduced semi loops that score all necessary agenda points in one turn while avoiding the use of AI CFO. Thus these decks do not build up a real infinity loop but 'only' try to win in one turn. One of these can win in turn #2!
I myself improved the basic idea that is introduced in this article and found a new concept that is much more efficient but needs an external trigger (you can find it here).
All real loop decks currently have to use two specific cards: The first is Pacifica Regional AI (PRAI) which gives you the ability to gain actions during your turn. There is no other card in the current Netrunner set of versions 1.0 and 2.1 that can do this. The second card is AI Chief Financial Officer. After having scored this agenda you are able to recycle your deck indefinitely and you'll never get decked by running out of cards.
Then we have two main flavors: One uses Team Restructurings, the other Chicago Branch. Both let you put advancement counters on PRAI relatively cheap. With the correct card distribution you can gain a fraction of an action each time you do a cycle. You advance one or two PRAIs and then use the gained actions to draw cards (normally with a scored AI CFO) and earn bits by various sources.
Using Team Restructurings is cheaper. You need one card (0.2 actions when you draw it with AI CFO) and 1 one bit to gain an action. The drawback is that you'll have to put quite a lot of them into your deck (Wyatt uses 11 of them).
Chicago Branch on the other hand costs more (3 bits for one action) but you'll usually need only 4 of them which gives you more space to build up your defenses. With this variant you can have up to 14 pieces of ICE for your corp and still be able to do the loop as easily as corps that rely on Restructurings.

But now head on for the old article:


Doing a little bit of math (it's my job ;) I found a working infinity loop for the corporation. Now stop laughing and relax. It really works, but it has one major drawback: It need's a complicated setup and a dedicated deck construction.

You'll need at least 34 bits in your bit pool. Better would be 37 or 40.
Hand: 1x Pacifica Regional AI (PRAI), 1x Chicago Branch (CB), 1x AI Chief Financial Officer (AI CFO), 2x any other card (preferably Credit Consolidation (CC)).

Then we start:

   * draw a card
   * 1. action: install and rez PRAI
   * 2. action: install and rez CB (32 bits left)
   * 3. action: advance PRAI two times, using CB. (29 bits)

At this point we have two actions (via PRAI) left. For every action + 3 bits we can now get 2 actions, which gives us 3 bits/action. Using 12 bits we gain 4 additional actions (17 bits, 6 actions left).

Next, we must score the AI CFO:

   * install AI CFO
   * advance with CB
   * advance with CB
   * advance (10 bits, 2 actions left)

If we have any money making cards left, we can now play one and use the gained bits to further advance PRAI. If not, we use AI CFO to draw five new cards. As we already have installed 3 cards, there are a maximum of 42 cards in R&D now. So on average there are about 3.2 money cards in our newly drawn cards. With these cards we gain bits and use these bits to gain more actions. In the process we install all installable cards until there are only operations left. From this point, the process can continue ad infinitum.

Why does this work?
Using AI CFO we only spend about 0.33 actions for drawing the money operations (1 action to get approx. 3 cards). So we have:
0.33 action (draw) + 1 action (play) = 4.7 bits (average)
which yields 3.53 bits/action. Using CB/PRAI we only need 3 bits/action, so we have a net gain of 0.53 bits/action.


Finally, the problems:
The setup is tricky. We need a lot of money and some ICE and three different cards. The current card mix already has some real life modifications, else you wouldn't need any Tychos, ICE or Accounts Receivable (AR) and not that many PRAI/CBs. In the best case (no ICE, only playing money cards) the loop can start on the 4th turn, but typically this would be the 6th or 7th turn and the worst case: never.

And as long as there are 4 cards other than operations in your R&D, the loop can break if you get subsequent draws of these four cards. Even with 3 nodes/agendas in the cycle it can still break if you only get ARs, which do not yield a sufficient bits/actions ratio.

But this has no high probability (anybody doing the statistics?).

[Not legal any more due to Tycho but there are plenty of ways around that]
