I've been running the core of Gerrark's Haley deck for a few months now, it is pretty good. It just says nope to so many corp strategies.
CI7 players - "Why you run so many Sacrificial Constructs?!"
Railgun - insta speed install of either Heartbeat or NACH following the power shutdown
Prison Decks - Employee Strike, Same Old Thing, Slums and Paricias
High Stakes Game/PU/PE - Heartbeat, Heartbeat, Heartbeat, etc
The only reason I haven't taken it to a tournament yet is that it is quite reactive. You're basically countering whatever the corp is attempting and then hoovering up the agendas that have all pooled in HQ in the late game. You might win all your games, but a few of them will end up as timed wins
The deck used to have Rumour Mill in there. In 10% of your matches it is the ultimate hoser card. I dropped it for Slums and Interdiction. Slums will provide a benefit in 90% of matches these days and Interdiction can provide RM effect on the turn it is played and is uncommon enough that it people don't think to play round it.
A cheeky Fall Guy might not be a bad idea, if you can fit it in, to counter all the Snatch and Grab, Liz Mills or Voter Intimidation that is going around.
