1: Nazca
Gragg
Get your F’s out for the Nazca. They had the misfortune of being on the same continent as Uruguay and Kuikuro. Between those two the Nazca never really had a chance to expand and snowball. They never got off the ground in Endgame. As their last act of defiance they died to Venezuela instead of Uruguay. That leaves the Nazca killcount at 1 and Uruguay’s 0.
