i've realised of a much more effective way of gaining points quite indefinitely, based on Conquest (which can report at about 20, 30 or 40 VP per 6-coin buy repeatedly), rather than Triumph (which is limited by total amount of cards and impossibility of regaining estates from trash). i've just reached 4827 VP in 13 turns at first attempt on game #34673394, with this set:
Special kingdom rules: Colonies, No Shelters
Required cards: Ambassador, Bishop, Goons, King's Court, Market Square, Rogue, Peasant, City Quarter, Priest, Fortress, Tomb, Donate, Conquest, Mission.
market square is quite annoying because of recurrent trashing decisions (to avoid gaining gold, that soon becomes useless and populates trash), so i'm considering exchanging it for working's village.
