David Liu's Corp Deck ("Damned if You Do, Damned if You Don't"):
3 x Tycho Extension
2 x Corp War
4 x BBS Whispering Campaign (with such a tight deck, these are better than AR)
5 x City Surveillance (you can use as few as 3, replacing two with TRAP)
4 x Roving Sub (not essential; can replace with one MSU, one AcRec, two ice)
4 x Chance Observation
4 x Scorched Earth (Urban Renewal is NOT worth it; it buys a very occasional
first turn win but is too expensive for "general flatlining" :)
3 x Systematic Layoffs
3 x Management Shake Up
3 x Too Many Doors (not essential; replace with Asp and Data Wall if needed)
3 x Quandry (TMD and Quandry are important for early Roving Sub/City Surv.
protection)
3 x Crystal Wall
2 x Mazer
2 x Endless Corridor (replace with one Quandry and one Mazer if needed)

total = 45 cards (again, keep your deck as small as possible.)

Happy running,
David
