Sure, I'll take a shot:
Conspirator:
+: [Cards >= 1 && Actions >= 1], [Actions >= 2], [Trash >= 2], [Buys >= 1], Warehouse, Cellar, Ironworks, Moneylender, Throne Room, King's Court, Pawn, Tactician, Loan, Spice Merchant, Stables
? [Cards >=2 && Actions == 0], Mine, Adventurer,
-: Witch, Young Witch, Sea Hag, Mountebank, Gardens, Trader, Swindler, Duke, Torturer, Ghost Ship, Familiar, Rabble, Tournament, Fool's Gold, Tunnel, Jack of all Trades, Embassy, Jester, Ill-Gotten Gains, Governor
Am I doing this right?
I don't actually get what's supposed to go in the '?' category. I mean, by default everything that's not in + or - is ?, right? There's lots of thing which won't affect my decision to go conspirator or not - I wouldn't buy them for a conspirator engine, but I wouldn't stop my conspirator engine because of their presence, either...
