This list is heavily inspired by Joseki's CtM list he won a local store champ with (https://netrunnerdb.com/en/decklist/47924/weirdo-ctm-1st-place-victory-point-cafe-sc-7-0-).
There are only 8 Advertisements. There should probably be at least 2 more Ads to justify Spark. The list worked out OK but I can't say this is any better than the CtM list. It probably isn't. I went undefeated with my Runner but this deck didn't actually get me that many wins. I also didn't practice with it at all.
Economic Warfare is a really good card though and obviously has potential in Spark Agency: Worldswide Reach. I loved watching runners try to play around it by sitting at 3 credits. That is just great for Spark.
