I'm not sure about uppers but Freaks/Ulu seem to work well together. My current deck:
I might give that a try, im not a huge fan of numar though so im probably gonna sub in nolan or eddie and than baldovino for daqun
Splata Cr or Baldovino
On your preset-- Taigo is outclassed by Dave, you've got plenty of attack manip without him anyway. Definitely switch them.
I see the theme of your deck is to threaten KOs and play mindgames, but a draw where you get only one of Oxen/Kayazan/Daddy Jones/Rubie will be pretty tough, especially if Rubie doesn't get her bonus.
For a DR-heavy squad that can still hit, you could bump up Rubie to Maurice and sub in Eugene for Noland. (Eugene is pretty much a mini-Wee Lee, which is why people like him). You lose a bit of KO potential but mindgames are even tougher with all the DR.
I actually switched daddy jones to eddie and moved rubie up to nellie, this was last week though when eddie wasnt banned and it worked pretty well,
this week im using http://www.urban-rivals.com/en/presets/?id_preset=2652260
