I've been playing Rezeki Wu for about 75% of my runner games since Rezeki came out, and think that the deck is very strong across the board.
Gameplay: The deck can get set up quickly with spec work and diesel to draw into important pieces, and can stimhack out the rezeki's in matchups where that is useful. Usually I find myself saving stimhack though to get an engolo out to trash an early jinja/daily quest or to stop an atlas or nisei mk2 from being scored early game. The nice thing about having kati, aesops, and rezeki's is that you have a ton of redundancy in your economy and can live without some of the pieces for a good portion of the game. Once you are set up you can just remote camp and poke HQ and r and d a bit if they are cheap to get into until you have enough memory to install the stargate to more or less lock out the corp.
In the tournament I had timed wins against Argus and Blue sun, and then lost to the same blue sun in the cut.
Overall I dont think I'd make any changes to the deck right now, it has game against almost every corp. I havent played the IG matchup though and in theory I could see that being pretty tough.
Thanks to Austin and Jamie for running the tournament, it was a lot of fun!
