Incidental Check

An aggressive denial Reina deck. Run hard from turn one. An early Desperado and/or John Masanori can be useful for getting extra from your runs.

Knights can be used to quickly defuse servers or snipe well defended agendas. Events like Dirty Laundry help you keep afloat as you put pressure on the Corp's economy (via Reina's ability and Xanadu). Parasite/Datasucker for additional griefing.

Keyhole is not a main strategy, but you can default to it easily enough if the remotes dry up. Move all Knights to R&D and just go to town. If you don't spot agendas, Keyhole economy next.

There are some good resources, as well as cards that can tag which is a bit of a non-bo, but if you're keeping the Corp poor enough, they're unlikely to stump up the cash to trash your stuff.

Some other cards for flavour:
Cyber Threat has a nice pseudo-FAO effect that combos with Masanori on servers that only have unrezzed ICE (i.e. facecheck without the tag).
Singleton Account Siphon for the surprise. I've played many games where when Keyhole hits the table, Corps give up defending HQ so this is a nice one-two punch. Same Old Thing can recur if needed. A couple of other singletons to help you out in a jam (e.g. Dyson Mem Chip for memory issues, Quality Time for digging or Jinteki glory runs if needed, e3 Feedback Implants for stacked bioroids and Knights)
Plascrete Carapace because Netrunner
