Leader: Sitting Bull
Capital: Little Bighorn
UA: Into the west - Empire enters a 5 turn golden age after expending a great person.Great people purchase with faith 50% cheaper, but spawn rate 50% slower.
UB: Fire pit (replaces forge) Iron based units cost no maintenance
UU: Reaver (replaces cavalry) Unlike other units, this one earns promotion for killing a unit.Each kill gives 1 level.At level 10 you can choose to expand the unit to gain a huge faith boost.
The UA is original, but I don't like being penalised for not having enough faith. It could work out quite well, I'm just not sure where I stand on it right now. The fire pit is a nice idea, but if you build it once, then all our iron-based units cost no maintenance, and there's no point in building it again to get the benefit. I like the Reaver, but it comes too late game to found a religion, but late enough to help with faith purchase, which ties into the UA. I would suggest changing the UB to help with faith/great people, and that's really about it.

This seems good, I'd just say that it's far too reliant on social policies. I think that you should change the civ to get slightly more culture, or make it less reliant on SPs, but otherwise I like it.
