7. Cree - Mekewap [5 - 3 = 2] I think Lavra is #1 by a long shot, so looking between this and the similar Kampung, I've got to vote the Mekewap down. They are very similar, but I've found Kampung to boost my cities far more in my games since the Mekewap can take good land and make it better, but the Kampung can take a nothing city on a near barren cost and make it into a great city. Mekewap just doesn't have that city spam ability that the Kampung does.
16. Indonesia - Kampung [5]
29. Russia - Lavra [11+ 1 = 12] I see a lot of people saying that they don't like the religious game, or that they don't have a playstyle that the Lavra accomodates. While the rules don't specifically state this, I always take these threads to mean the most powerful, and whether you think the Lavra is balanced, fun, or ruins an aspect of the game; there is no denying its power. It's available cheap and early, it wins you the religion race every time, and it is so overpowered that you get great people with no effort. In every Russia game I've ever played, I've gotten to the point where this thing also generated money as I was selling great works to other players just to make room for the new ones I was about to create.
