Why do i think that he will face shock promo, becouse hes SB xDD and i think he will face shock at some point but well maybe i "overreact" becouse iam used to deity.
Maybe i do overestimate Construction, to be honest iam fan of Prets rush with AC.
AC isnt guy witch is good to oracle construcion.
But this map 2 gold start, lots of forest, SB as opponent just looks to me like its reasonable.
Post the starting save (at least if there actually is iron accessible) and people can have a go with both approaches
yeah
Proper approach for oracle constr. its like Izuul mentioned skip all and get writing 1st best leaders do to this are Cre ( duble prod. speed of Libary) witch starting techs are close to writing ( example - Hatty, Louis Cre, Ind starting techs agriculture,wheel with him Oracle Construcion isnt too hard even on deity).
You went BW 1st so its allrdy too late to run 2 GS and bulb math, and you have 2 gold start its better to work just on gold its huge reserch boost and you wont loose GP.
So becouse of that i would just try tech self tech allway there. I pref going AH -writing - math you will have early math choops witch can be used to like choop out Lib in capitol, or you can prechoop some forest and choop out Oracle as well.
So that how looks proper Oracle attempt in this case at lest i think so ...
You dont need Marble.
