Build for Skull Merchant

So I'm thinking about getting skull merchant cus she looks cool and I have a gut feeling that if she is utilized correctly she isn't as bad as people say. My idea is to mainly patrol the same 4 or 3 gens due to her ability to be oppressive with a decently large area. What build would you guys recommend, aura reading, gen regression? And am I off on how she should be played? Let me know y'alls thoughts.
