alright so i think i found a pretty good supremacy strat with japan (plz don't say their so OP any strat is irrelevant, because they don't have op rush.) alright. so age up with 13 vils putting them ALL on food. if you can get the food upgrade, not totally necessary. once you age up, switch 3 villagers to gold, 4 to wood. then put all new villagers on food. use great bhuda when you age up. right when you age up use the spy ability and look where his hunts are. right when you age up send 5ashi and buy 5 ashi and send them at his hunters. keep producing vills and putting them where needed. (always more villagers! and get market upgrades in age 2 if you haven't already) then keep getting ashi+yumi and take out his hunters then take out his base.
necessary cards cheap/ better shrine, 5 ashi, 5 yumi. 3 samurai if you want but i never use them doing this. i also usually use chornonido and sumptuary laws and the 4 villager cards.
i have used it 10+ times. only lost once to someone who fast fortressed with brits and hit and ran with longbows.
any tips/criticism would be aprreciated
I guess the only way Brit can beat German is they have Americans helping them.
