Murder Inc.

This deck looks at Meat damage primarily as a way to scare and tax the runner (similar to the way a lot of Jinteki decks look at Net damage), which should explain some of the deck-building choices. Data Raven and Bernice Mai are there to support Dedicated Response Team, which is the primary means of punishing the Runner (usually try to have at least one DRT hidden behind a Chimera or Ice Wall early game). GRNDL gets fast economic starts and so a strong mid-level ICE strategy with Hive, Chimera, etc. is easy to sustain, creating a very imposing problem for the Runner.

Once The Root or a GRNDL Refinery is safe behind an ETR ice the economic battle is effectively won, which helps lighten the need for Operation economy with this deck. Instead we have Interns to recur Ravens/Mais or Economy assets as needed, and Witness Tampering essentially powers up all of the Tracer ICE in the deck by ridding the field of free BP credits.

Once The Cleaners is scored everything this deck does becomes extremely dangerous. Combine with Private Security Force behind the strong ICE this deck runs and and there exists literally no room for error in the Runner's game.
