I've made some changes from my initial build after trying her out at a local tournament. I must say, the black mail playstyle just got real with Valencia.
I played her as a control deck; trying to get as much bad publicity on the board as I could, and after that smack down an Itinerant Protesters and try to get down a sweet wanton destruction. It also works like a charm with Vigil, making the corp wanna go under their card limit, thus reacting to your action instead of vice versa.
Second approach is the ultimate doom machine that was born with Eater and keyhole combo. Making it quite easy to access r&d when you can break anythig with an AI corroder.
For both tactics, we want to ignore any remote scoring server, until we can tell they are trying to score (ad they really want to do that fast against this deck). At that point, make sure to have a Blackmail ready or aggressively draw for it. And if they start scoring from a sansan, try to have a singularity in your hand and raze the entire remote, making life eve harder for the corp.
I have not yet met any chell game players, but I believe you can safely run all advanced cards with 4 cards in hand and a #I've had worse in the hand, using #deja vu for getting then back. Losing programs and getting brain damage early are what we anarch does the best.
Have fun playing this amazing control deck!
