Shoshone offer a few great tactics.
The free tech is particularly interesting because you can get it whenever you want to. Find an ancient ruin at the coast or near some mountains and you can easily "trap it" with a few pathfinders or your (advanced) cultural borders. It's like a free Great Library with a lot of possibilities. Obviously Philosophy slingshot comes to mind (fast NC and temple spam!!!) or if the melee line gets a well deserved buff, rushing to iron working might be a good plan, too.
On emperor or below, even fast Theology might be possible with Great Library plus free tech.
