This deck went 4-2 during the SE Regionals, loosing to the 2nd place finisher and someone with astounding luck/psychic powers (5 blind hand accesses, pulled the 1 in 5 4 times). The idea is simple: rush agendas hard.
I focused on cheap ETR ice, or ones that offered unique defensive advantages. Wall of Thorns can be a great rez off an early Hedge Fund to either keep runners out of R&D or create a scoring server. Never underestimate the 2 net damage they get from face-checking it, particularly on a tight clock. Inazuma Helps to "reactivate" ETR ice once the runner has a breaker, and Guard is a Sentry ETR that also keeps out Inside Job and Femme.
Economy is focused on providing quick cash bursts to power scoring and to generate enough to rez a San San City Grid within the first 2-3 turns to power out agendas.
Some plays that I've found effective within the deck:
In general the rest of the cards are there to slow down opponents: if they are trashing everything, drop more Mental Health Clinics and make them waste credits and clicks. If they hit everything you Mushin, Mushin a Shi.kyu and let them eat that. This deck can "turtle" if necessary and guard centrals and rely on ToL to score 2/3s (only need 3 of them), so you can adjust your play style a bit (rather than pure aggressive).
Its true I've not played against a Siphon heavy deck with this thing: I can imagine that would be rough since I can't ice heavily, but I'd probably be a little more conservative against Criminal and Guard HQ so they couldn't get in and turtle to ToL out agendas.
