Fairly new to NetRunner but am loving it. I just recently got my 2nd core set so I can build optimal decks. I start with Anarach and I've stuck with them. Here's the deck I'm running now:
1x Gordian Blade 
2x Ice Carver
2x Public Sympathy
3x Test Run 
1x Magnum Opus 
3x Liberated Accounts
3x Armitage Codebusting
3x Sure Gamble
1x Easy Mark 
This deck is built around Test Run, Wyldside and Djinn. Wyldside seems particularily powerful to me as an engine. You loose an action but each action you DO spend is incredibly efficient. With Public Sympathy out it also negates double Scorched Earth. The number of options you get via your cards in hand offsets the loss of action, I hope. I love the Anarch breakers because they work so nicely with the ICE-strength reduction. Cheap runs!
Concerns I have are: Should I be playing Magnum Opus? If I only have 3 actions per turn is it worth using? Can I just lean on Wyldside to draw me into any of: Codebusting, Liberated Accounts, Sure Gamble? How can I improve my economy?
Is Test Run worth it in a deck with 3 Wyldside? I'll have to add more ICE-Breakers but I will get 9 Influence to spend on other cards. What are the non-Anarch cards I really should be running here?
Thanks for any help/advice in advance.
