Faust is strong and it has crazy numbers, but it can be played around. 3+ str ice, multiple subs, any kind of damage that can happen during runs, etc. The reason it's so prevalent now is because it's easy to build around. Pick any ID, shove in a bunch of draw and a Levy, sprinkle in 1-3 Fausts and you've got a deck that can win you some games. Doesn't mean it's optimal, but it is easy.
What I'd like to see printed is more direct AI hate. Until this point there was little need for the likes of Swordsman. Now we need some neutral/easily splashable AI dedicated hate cards that aren't solved by including stuff like Mimic/Corroder that are being played in-faction anyway. Putting Faust on the MWL doesn't help with the fact that Anarch has all the optimal support for it. Anarchs still play Parasite regardless, same will happen for Faust. Actual answers would help more.
