I think that right now, the answer is Foreign Wives. When she was released, her ability forced players to rethink how to go about drawing and making rescue attempts and that used to be the way that Uzzah was up until the last year or so, when Isaiah and Daniel became popular (and Moses became more common, especially in conjunction with Angel Under the Oak). Even now though, the possibility of Uzzah can make a player rethink a rescue attempt. The possibility of a character forcing people to rethink how they play the game is far more effective than any actual ability is, and at this point, Foreign Wives is far more effective than Uzzah is, especially because there are so many effective-but-negatable evil characters out there. Her initiative isn't the best (though the volume of rescue attempts that do give her initiative is much higher than it used to be), but she still has access to two of the best evil enhancements in the game (Plot and Stone), not to mention every other non-civilization specific evil enhancement. Her being Egyptian lets her naturally splash into those decks, but even better is how she functions in a Canaanite deck. A lot of early versions of the Pharisees defense that was popular at Nats utilized her, Lot's Wife, and Stone, and I even played around with Fortify Site in that deck to moderate success. On top of an incredible ability that forces people to rethink the game, she's probably the most versatile evil character right now.
I am looking forward to when I can play others online, my first decks you will beat me hands down, but I rethink based on every match, I learn, and come back stronger, with this strategy, I hope to eventually be a top contender.
