African economy

I dunno has anybody tried this

Play as Hausa, have an Ethiopian ally, and some other allies that can eat animals, play on maps with wild African cows

Have all your Sanga cows(18 of them and 2 big bennies) fatten first then send them to work on farms(need a card for this), have your Ethiopian ally send you all his Zebu cows(and 2 big bennies) and sheeps and make cows work on farms, have allies herd African cows(Zebu or Sanga) and give it to you and use them to work on farms, also have allies make livestocks(like Sheep Cow Llama) and send them to you.

Just theory crafting, dunno is this possible or not, but if possible then you can have an influence income that is so gigantic that you can spam units endlessly, also the cow working on farms means you dont ever need villagers, can have 200 pop for army.
