This is the deck that carried my mediocre Kit deck to 3rd place out of 17 at the Uncle's Bellevue store championship. It ended up being the best performing corp deck at the end of swiss and got me to third in the cut.
The key to this deck is that it is able to keep the runner consistently at 0-1 credits, which helps reduce the runners options. The challenge is getting the runner to over extend and get them to a low enough credit pool where you can really start to leverage the Spark ability. With only 12 advertisements, your goal is to save them for maximum effectiveness, draining a credit from the runner every turn is cute, but rarely effective. However, if the runner gets to a low credit point, like after stealing an NAPD through a Predictive Algorithms or after trashing a Public Support, you can then get the runner into the awkward poor place against Spark, where you keep them floating under the 4 credit mark.
In addition, this deck forces the runner to spend money on everything, Predictive ends up being a work horse of a card. Not only does it enable News Hound, it also lets you do annoying things like dropping the runner from 2 to 1 credits when attempting to steal an agenda or looking in HQ/RnD.
Funny thing about this deck is that it was initially a clone of the Dedication Ceremony + Reversed Accounts deck, however, when I first build it I forgot to include the Reversed Accounts. I played 5-6 games wondering why I always drew Dedication Ceremony but not Reversed. Even though I forgot the main combo piece the deck was still performing really well, so that is why the Public Supports came into the deck, and it slowly morphed into the deck before you.
Won't forget our Lower-bracket finals match anytime soon. It doesn't get more epic than "click for three credits, run R&D" while the last point in the form of a Public Support sits comfortably in an impenetrable server.
