A few days ago Warlord Bot constructed this fantastic, exploding, do-nothing engine out of Universities, Ghost Ships, Advisors, Warehouses, and Moats. (Well, one thing it was doing was Ghost Shipping me every turn) It was always discarding coppers with it's Warehouses, so it could never afford more than a University, and each turn it was gaining multiple "engine" parts with it's existing universities. I present to you Turn 20, in which Warlord Bot plays 28 actions, gains 1 Ghost ship and 5 copies of Traders via University, apparently setting of it's internal piledriving alarm along the way, decides it's time to start greening and ... buys an estate. Maybe next turn it was going for the coveted Trader Megaturn and was going to Trader 5 Ghost ships into 25 silver?
Warlord Bot: turn 20

Embarassingly, I was more or less buying the same cards to no useful end, just with enough common sense to get some treasure here and there, which enabled me to snag a few Dutchies when I saw where Warlord Bot's engine was heading.
