Expedition, Hamlet, Stonemason, Gear, Warehouse, Philosopher's Stone, Conspirator, Death Cart, Port, Counterfeit, Counting House
There's a perfectly good Conspirator chain there basically begging to be set up. You have Port and Hamlet for +Actions and +Buy, Counterfeit to trash, Gear for additional draw if you need it, and Stonemason to quickly gain a bunch of Conspirators. There's even Warehouse to sift when you start greening. I wouldn't have even considered the sloggier strategy here.
Well, the opponent tried the conspirator engine, but, well, it didn't pan out. But the idea is thus that I got lucky? Which is very plausible, of course.
I play for fun, so sometimes I just try silly things. Let's say... not always to great success, haha.
