Disclaimer - my recommendations are formed based on me facing Guild decently often, and what I would do if I picked up Dashel.
I would recommend the three remaining guard boxes (Run Them Down, Crime and Punishment, and Rank and File).
This gives you Guard Patrol (Dashel 2 Summon, mounted guard demise), Mounted Guard (solid hire), Guild Hound (Disease Containment Unit summon), Executioner (all star beater minion).
After that the Guild Staples of Pale rider, Lone Marshal, Guild Steward, Guild Mage, and Guild Lawyer are all good purchases.
