Select one neighbour, declare war and go pillage the nearest cities, engranging a hefty amount of culture and gold (to reimburse the lost troops). But don't take their cities.
Once you have taken all you can, make peace with them, and go look for the next prey (bonus point if you can manage conjoint war with a civ on the opposite side of the target).
The aim would be to be almost constantly at war with one civ only, and to keep pillaging to produce lots of culture (and hamper the neighbours). The aim is a culture victory, the extra culture being transformed into more artefacts.
Espionage => get caught => Enemy DOW's you => Free War support for bonus Combat Strength, which helps conserve health and village more.
