I ran Healing Your Brain Harmony Medtech in a DC store tournament yesterday and had pretty good success with the deck (only losing with it once, to a lucky R&D run).
The main ideas behind the deck are: make tons of money, build a very taxing scoring server (including good old Caprice), install advance advance a PriReq, then next turn score it and rez either Janus (preferred) or Heimdall 2.0.
Inazuma->Janus is ridiculous, and Inazuma->Heimdall 2.0 is nearly as good. If they hit both, they're dead.
Shi.Kyu is an MPV, forcing the runner to steal half your agendas. Another amazing card was Future Perfect. I piled these up in HQ (again, you want to score the PriReqs, not these) and you can even Celebrity Gift them to the Runner. This only entices HQ runs even more. If you have even a few taxing HQ ice, this often results in a very frustrated runner.
I will probably mess around with this deck some more, but I took it, completely untested, to a store tournament and it preformed really great. I love this new ID!
How long do your matches take on average? All 3pointer Medtech builds i have played so far felt very slow. Are Jackson + Shiro enough to get to your agendas fast?
I like the idea of a 3point-deck without traps though. Seems to be interesting :)
