OK so I will look at who picked in what order and tell you if they were bad or good.
1) Netherlands pick: This is worst pick in whole draft.

You guarantee last leader pick to get crummy civ. Starting techs are nothing special. UB comes very late and needs water map to be good. UU is a ship lol. This is terrible first pick.
2) Wang Kon: This is pretty good pick. You are only one with Fin in whole game. Pro sucks but oh well. Not bad.
3) Catherine: Very strong early game leader. Cre to pop borders and Imp for lots of settlers. Hope we dont start next to them. I think there were better leaders here but pick isnt terrible. Might work out good.
4) Isabella: Best pick.
5) Shaka: OK leader and still gets Exp. I think Agg is not so good because economy > rush in these games. But you are only Agg leader in game which could be good. Would have probably picked someone else though.
6) Bismarck: Pretty good pick, one of the stronger leaders. Good economic traits. No problem with this one.
7) Egypt: Silly to pick civ before leader unless civ is really good. Egypt is OK but not that good. Waste of a pick. Now you get #9 leader pick instead of #6. Egypt not worth that.
8) Washington: This is rush leader. Exp/Chr is all about early slaving. Must watch this player. But rushing normally loses this game so I wouldnt take this leader. Chr kinda sucks.
9) Asoka: No Exp or Cre on traits. Org and Spi are both OK but I think this is kind of a weak pick. Feel like there were better options here.
10) Louis: This is great pick!

We had Louis ranked #2 after Isabella and he gets Louis with #10 pick. Cre/Ind is very strong economic traits for this game. No clue how Louis lasts this long.
11) Babylon (+Louis): This civ is OK but there were stonger picks. Techs are good (Agr + Wheel). UU is pretty meh. UB is bad. Colosseum with extra health is dumb. OK not great.
12) Vikings (+Asoka): Terrrible civ!

You have weakest starting techs in game, Fish + Hunt. Scout start. UU and UB are useless unless this is big water map. Not sure what they are thinking.
13) Greece (+Washington): Terrible civ!

You also have weakest starting techs in game, Fish + Hunt. UB is awful, coloseum with +1 happy. UU is axe that doesn't die to chariots. Thats OK but pretty weak. Civ pick doesnt fit with leader at all, since Wash is rush leader. Why not take Mongolia or Carthage and rush? I dont understand.
14) De Gaulle (+Egypt): This is worst leader in this game. No Exp or Cre. Ind with 3 other Ind leader. Chr very weak trait. Chr is good for rush and Egpt also good for rush - but Ind is terrible for rush. Dont understand this pick. If synergy is supposed to be Chr + Egypt obelisks then that is stupid. This guy will probably build Stonehenge which is noob build in these games. Think this is terrible pick.
15) Sumeria (+Bismarck): Terrible civ!

You have UU that is worse than normal axe. You have UB that offers no advantage. Courthouse that comes 2 techs earlier on tree. Starting techs are good but this is awful civ. Why would you pick this when CHina, France, England all available? Is stupid.
16) Zulu (+Shaka): This guy didnt need Unrestricted leaders lol. This is a pretty good pick though. UB is good and paired with Agg leader so its cheap. UU is awesome at choking. Hunting start is bad though. Pretty good combo overall. Good for rush/choke espcially.
17) England (+Isabella): Good pick.
18) China (+Catherine): This is also a good pick. China never should last this long before getting picked. Awesome starting techs and OK UU. UB even has synergy with Cre trait. This is one of the best combos.
19) Arabia (+Wang Kon): Terrible civ!

Starting techs are pretty bad (Wheel + Myst). UU is a knight that doesnt need iron, sucks. UB is a library than can run prists - which you wouldnt want to do anyway. This is just a bad civ.
20) FDR (+Netherlands): This is OK pick for leader #10, really dumb to give yourself last leder pick though. No Cre or Exp. Traits are OK for economy but they are second tier. Taking Dutch first really screwed this guy.
Here are best combos IMO:
Catherine/China
Isbella/England
Louis/Babylon
Shaka/Zulu
Bismarck/Sumeria
Wang Kon/Arabia
Asoka/Vikings
FDR/Netherlands
Washington/Greece
De Gaulle/Egypt
Put them in three tiers in rough order. Top three are all good combos, Louis a little lower than the others. Middle three all have some kind of flaw in them. Shaka is best but weaker economy. Bismarck and Wang has lousy civs. Bottom four are weakest pairs. These are bad civs and bad leaders. Maybe they will surprise but they have uphill battle.
I think Ive learned that many people here dont know what to do after best civs/leaders are banned. Leader picks were pretty good but many civ picks were just terrible.
