I think zer0 is a brilliant anarch card. I think Clan Vengeance is a bad idea that was only saved by the lack of repeatable self-damage in the game. Admittedly I don’t like cards that turn the game on its head: I think they tend to be either pointless or oppressive without an in-between. (Data Leak Reversal, Counter-surveillance etc). The new Weyland ID is in this frame as well. If there is a Clan Vengeance equivalent for Bad Publicity the ID will be oppressive.
It is far worse when this in the runner side. Netrunner is a game of attack against defence. If the runner doesn’t run then the game becomes tedious. Not so bad on the corp side due to the structure of the game.
