What StephenE said, really - I would consider cutting Femme instead of Mongoose, if you wanted to try out Lustig. Except, in all honesty, I don’t think I would bother. It’s massively inefficient against the key ice that you really want an early Mongoose for (Architect), and its barely superior to Ninja (the more damning comparison). It will serve you well against Archer, and perchance Gutenberg, but it’s just ‘by the numbers’ poor against the majority of mid-range sentries. Do feel free to test it out, of course, but I don’t imagine you will be thrilled by the results.
In my mind, the only one of the new Crim ‘con breakers’ that is particularly decent is Abagnale, as it saves you a fair amount of influence over Gordian (or Zu.13), whilst also being solid against several common code gates. Even there, I think you would frequently miss Gordian’s less-clumsy, 1-for-1 strength-boosting and, on occasion, the strength retainment. Depending on the popularity of Skorpios though, you may just have to bite that bullet.
