I disagree with banning a card that breaks open one matchup, because playing that card already is trading some small amount of percentage against the field (for lack of consistency, and sometimes influence) for a big swath against a particular deck. Most of the bans-for-destabilizing I think could be MWL, because I don't think most of those core hate cards would be broadly played if they cost both influence and deck space. Both are very tight these days, and the advantage of MWL is it makes them even tighter. That, and there's a part of me that'd like to believe banning should be for cards that are permanently destabilizing - that punch huge holes through the meta. If a card cracks open a particular matchup, the meta can shift around that matchup until the hate card becomes less prevalent and it shifts back again.
If I were czar, I'd do this:
Faust (sorry, kids, we've been abusing our toys), Rumor Mill, Sifr (gj Damon)
Temujin Contract, Blackmail, Aaron Marron, DDOS, Sensie Actors Union, Friends in High Places, Medium, Employee Strike* (scandal!)
Suspect List (aka I could be convinced these deserve MWLing)
Eli 1.0, Desperado, NAPD Contract (also scandal!)
Usual Suspect List (aka I could be convinced these deserve to come off)
Cerberus "Lady" H1
*This one probably deserves a special defense. Employee Strike is a card that I think punches too big a hole in a core part of this game, which is building around IDs, and it just encourages lazy "my current, your current" counter-play. I feel like Strike, more than Feedback Filter, makes Jinteki damage matchups less interesting.
