Came in first playing this list during the Cache Refresh side event at UK nationals (18 people). Format was 5 rounds of single side Swiss, with bidding. Since I had no clue whether it was worth bidding anything, I just bid 0 on Los when I had the chance; none of my opponents seemed to mind so I just played Los 5 times.
The list itself is based on the one which won Cache Refresh event at German Nationals. I chose to play H&P iso C&C since the deck has enough econ as it is, and I like spamming legworks to close the game faster. The express deliveries did some good work as well to find either the tech cards for a specific matchup, or a timely siphon. Since crimson dust was legal, playing caldera over feedback filter and Aumakua over Mammon was a no-brainer. The turtle was utterly bonkers, single handedly winning me every game. If you can setup with an early temujin and turtle to get upto 5 counters, the corp will have to slow down a lot to ice all servers and spend time purging. By then you should have your other breakers online to legwork all the agendas which the corp is inevitable stockpiling.
During the event I beat Sync, Skorp, CI, Sol and HB. I did go to time against Sol and would have probably lost in the long run, as he was playing a lot of AI hate and high strength tracers which I couldn't profitably break.
