With Femmes like these, who needs enemies?
In the past, I've been hard on Magnum Opus, saying it doesn't have a place in stealth builds, and that it's too slow to get off the ground. But now that the moon is setting on the Lunar cycle, corps are also slowing down; I've seen more and more glacier builds pop up and Kati and ProCo can sometimes have trouble keeping up. So I've tweaked things a bit and found that by adding Femme Fatale into the mix, a lot of the previous problems I've had navigating early servers and managing stealth credits have cleared right up.
Femme combos beautifully with Kit's ability. Test Run her when the corp is trying to sneak out an agenda behind a two-ice server, and bypass the innermost ice. Scavenge her if you need to, otherwise let her go back on the stack and discard her to be used for a future Test Run if you don't want to hard install her with Mopus money.
With the corp economy trending toward the beefier side, I've brought Vamp down to only one copy - great if you use it, no big loss if you don't.
Deus X recursion is your protection against net damage, and just one Plascrete should keep you safe enough from the Scorch to make it to 7 points. And Escher will win you games. Load up a server with all code gates and go to town.
