My input;
Civics-
Representation along with Mercantilism is a Must.
Nation hood for the Labour civic, 25% espionage (fits the Variant ) and +2
Once the Slavery whipping is over with, and we look to swap out of Organised religion, I feel we also need Caste System, for the +1
and unlimited Specialists in Scientists, Merchants and Artists. Grow the cities to the point where, whipping loses is effectiveness and working tiles, workshops and farms is more beneficial.
Economy, I've covered with Mercantilism, we are at war to save the world.
Organised Religion for the whipping effect, with a eventual swap into Theocracy. Of the 6 cities that don't have Buddhism, only Capital city is a major one, and not a Troop producer at that so
So what does all this require, a trade for Constitution. Chemistry is out there, and the age of Privateers is over, before we even arrived there.
Definitely swap in a golden age, pump out an Artist from Seoul. hold till objectives are achieved, saving 5 turns of anarchy.
Going Theocracy, which is Zara's Favourite civic, will help there, even with the Heathen religion modifiers.
But!!!!
Long term, Zara is the Threat, We'll have to go to war with him as the permanent war target to slow him down, he has Communism, is in state property, Darius is in free religion, Favourite civic.
Unfortunately, they are both pleased with each other, and will trade freely. We're going to be caught up in war, and isolation from now on.
Caste system to pound out those troops/ships. Spying to watch the others, Theocracy to bolster the troops morale, Representation to delude the masses.
We must fight to save our Glorious revolution, and the world from these other despots.
In fact, I'm going to use the whip heavily in my turnset. 
Still have to catch up here. But if I'm very lucky, I may actually contribute before the game is over!
