I've just played an interesting game against the Goko bots where I embargoed the colonies just so I would get gains curses that could be salvaged next turn for extra buys. You need to do these sorts of things when you can play king's court on pirate ships for 22 tokens each. Final decks:
DG : 5 Laboratory, 4 King's Court, 3 Pirate Ship, 1 Tactician, 1 Salvager, 1 Graverobber, 11 Colony, 3 Province, 7 Curse
Lord Bottington: 1 Copper, 3 Estate, 2 Province, 1 Colony
Banker Bot : 1 Copper, 3 Estate, 2 Province
