Desert Folklore is still terrain dependent, also if you spread it to your neighbor who also has some desert, they'll found a religion too and start competing with yours.
I would move Dance of the aurora and Stone Circles up. Stone circles is not terrain based, since marble and stone appears everywhere, and fewer numbers yet +2 is actually better than more and +1 faith, since you don't have population early to work that many tiles anyway. stone circles even makes desert stones good with +2 hammers and +2 faith.
Dance of the aurora is certainly not bottom tier, it fits nicely with terrain dependent ones. You are forgetting the some maps do have a whole bunch of tundra hills that can be mined or even farmed. I had a map once where a city could work 10 tundra river hills. It was giving +20 food, +20 gold, +20 hammers, and +10 faith during a golden age.
Instead of "Top Tier", you should call it "you can't really go wrong with this" tier.
And instead of bottom tier, you should make a tier called "Foregoing religion" tier, If you get pantheon by accident and you don't plan to go for religion since your friend is playing Byzantine or something I guess. Monument to the gods especially, falls under this category.
Meanwhile, Religious Settlements and Ancestor worship is trash. Everybody either moves too fast in tech for any puppets to build shrines, they'll often build stock exchange before they'll build one.
Also, if you are going wide, Goddess of Love is much more reliable.
Also2, I was wrong about followers, but it still does only kick in if the city is following the pantheon though.
