The deck tries to win via two different routes: aggressive early runs without breakers (backed by Account Siphon/Vamp and Whizzard's innate trashing credits) and a quickly set-up deep dig on R&D with Djinn carrying two Mediums (preferably with counters from Grimoire), powered by Parasite (through Clone Chip) and Datasucker. This is also where Demolition Run and Stimhack come in.
Unless facing Weyland (where there is definitely still a 50 % chance of victory) this deck is brutal: massive economy (Siphon, Liberated, Kati, Sure Gamble & Stimhack) + Crypsis + precision strikes = success.
I've been playing this deck for around three months (at first in tag-me-style with Joshua B. and DLR and The Personal Touch for Crypsis for more focused runs) and it is highly disruptive to most Corp game-plans and just ruthless to HB/NBN asset-based economy (Whizzard makes this seem obvious, but Parasite/Clone Chip really pushes it to the next level).
