I know the Muisca have been done but I thought of another design for them.
Muisca
UA:
Gautavita Worship- If a city has a gold resource in it's territory or has a trade route with a city that has a gold resource gain +1

faith and +1

culture for every other citizen in the city.
UU:
Iraca- Replaces Missionary. Yields +2

and +1

when stationed in a city. Gives +2 experience per turn to any unit on the same tile it is.
UNW:
Sue Temple- Replaces Grand Temple. Along with normal effects it yields +2

happiness, +2

culture, and starts WLTKD in all cities.
The Muisca had lots of gold (some which was imported) and threw gold trinkets in lake Guatavita to worship said goddess. The Iraca were the priests who helped council in times of peace and war. The Sue Temple was a temple for their sun god and they threw a festival once a year for celebration. I was considering using the Gueche as a UU but Leugi already has that in his Muisca civ.
The Muisca are the source of the legend of El Dorado. This gave me the idea for an alternate UA something along the lines of,
UA:
Legend of El Dorado- Gain ??? whenever another civilization discovers tiles and cities belonging to you.
My thinking being the conquistadors explored Muisca lands looking for El Dorado but in real life the Muisca didn't really gain anything from that
