@Patton think i teched Agri, mining/BW first, and settler with size 2.
Settling on PH speeds up things nicely early (besides research)

Bit faster worker, and only improving corn and 1 mine needed.
Hmmm. When did you get your settler? Just curious.
Let's assume 18 turns for the worker, 11 turns (was it?) for a warrior while working the corn tile, then you have gone straight for settler for ~14 turns.
I wonder if my pattern had some justifications.
Since I had wheel, I had in mind to do something a bit outrageous (and considered madness on deity) : stealing a worker. I was glad to find Lizzy and she didn't meet anyone the moment I stole the worker(known thanks to EP).
In the line of thought to defend myself and ultimately thanks to warriors get 2 woodsman II axes (enslavers), I chose Mining --> BW right away.
Good sides:
I know where is copper as fast as possible and I can connect it.
Building a settler with imperialistic trait makes the use of green hillls as strong as using corn I think ; 2

(capital) + 6 (hills) + 4

(IMP) for a total of 12

per turn. With the corn, I think we get instead 11

per turn ( thus the settler goes out one turn later or even more with chopping?). Indeed copper in BFC helped even more but I ignored it in my calculi because it is kind of factor we can't ganrantee usually.
BUT, there is a downside of a corn not improved yet: once the settler is out, another one of warriors are best given the impossibility to grow more efficiently.
Anyways, in a really early war, I wanted to be mobilized fast to defend and milk some GG points.
All in all, conservative play and cuirassiers invasion are best and I would have probably failed at one moment as I had in mind a catapract invasion along Engineering+Machinery bulbs (I chose Poly instead of Med for Oracle). With those crazy techers, castles would have arrived too early I guess.
Now, I have to wait 4 months before next deity challenge. Time to practice...
