I have a Mono Uppers Deck that I'm planning on adding Kazayan to when I get the Clintz.

Right now I have
Burt
Harlod
Jose Star
Maurice
Nellie
Oxen
Rubie
Samantha

I'm also thinking about possible splash cards, advice would be appreciated

I like Spiaghi as a splash card instead of Samantha
Personally I would change Maurice to Lady since you have 1 free star space
or Burt to Kazayan like you said
