You can probably build an Engine here with most components, because you have the time to do so.
I might even open Workshop/Death Cart to grab Caravans, Shanties and Cellars along the way.
Don't ignore Counting House, because it can grab those Cellared Coppers right back.
And KC-Rabble every single turn will cause a lot of dead turns for the BM player.
You have to be patient thought and really hammer those Caravans, they're quite important, otherwise the junk will cause you to have many single KC-Terminal turns. The power of KC lies in connecting with something good; Caravan (and Cellar) make that job much easier.
Abandoned Market seems like it would be a good opportune gain, but would you really risk getting many Ruins to get it?
