There are a lot of good, powerful cards in Android: Netrunner that haven't found home in a deck yet. And there are decks that might not be particularly good, but that could be much better with some tweaking. This is a thread to help each other find a good way to put those cards to work.
Here are a couple of mine:
Midway Station Grid: This is an incredibly powerful card which had the misfortune of being reborn in the wrong card pool. There are very few pieces of ICE with multiple subroutines and their natural partners in crime, 5/3 agendas, don't have very powerful abilities.
I used to run it in HB alongside GRNDL Refinery and AggSec and it was extremely powerful but I think it might also be playable in either NBN or Weyland. The problem is that I don't know how to spend my influence.
The Board: This card has one of the strongest effects on the game, yet it requires you to do the impossible: Build two different servers, one for The Board and another to score agendas on. I think that when that NBN Studio comes out, this might see play but for now I struggle to find a way to keep it on the table and score at the same time.
What are yours?
