- Aztecs (+4 attack from Garland Wars)
- Maya (+40HP from El Dorado)
- Inca (More Armor, Fabric Shields)
Eagle vs. Eagle its Mayans>Aztecs>Incas
Note Garland war’s give +4 ATK and Incas are cheaper
I would give it to the Incas because of the sheer absurdity of the Kamayuk/Eagle Combination if you can get it going. This is in addition to easier Castle pushes. Their Arbs are as playable as any. If they counter with Longswords, you have plenty of options.
Incas until castle age, aztecs until mid imp, mayans after mid imp 11.
