Dirty Laundry is, no doubt about it, a great card. However I believe that it gets mindlessly thrown into a lot of Runner decks and used in ways that are counter-productive. I see people throw away a DL on the first turn by running into Archives despite not having any of the support pieces installed, and I shake my head. Prepaid VoicePAD can help you get a better return on investment for Dirty Laundry but it's still going to be a far worse Sure Gamble when you play it unless you're getting an ancillary benefit for your runs.
This is a card that belongs in a deck which wants successful runs for MORE then card access. Desperado, John Masanori, Grifter, Datasucker, HQ Interface/R&D Interface, these are the cards that should be your combo pieces to make Dirty Laundry an actually worthwhile inclusion in your deck. For those Anarchs out there who like to use ICE destruction and economy denial tools to break open a hole in the corporations' armor, then attack with cards like Medium, Nerve Agent, or Hemorrhage.... Dirty Laundry is for you!
But, if you are habitually using Dirty Laundry to get the net result of an Easy Mark, then you should really rethink whether it belongs in your deck.
