Regarding Nuada, I don't think the +1

gold on

city connection did much to this pantheon. It is still a very slow pantheon that just takes too long to scale, not making up for the loss of the strong early game provided by other Celtic alternatives.
Picking posts from January:
I didn’t say anything about Nuanda because I think it’s not just a numbers tweak there. Nuanda needs a rework.
it’s supposed to be the big

one right? Why does he have a scaler off of

science generation, but 0 additional science?
Nuada is a combination of the old versions of Commerce and Wisdom pantheons. The old versions of them were as this (as seen
here):
(old)
God of Commerce
+2

Gold and +2

Faith from

City Connections, +1

Faith for every 20

Gold per turn.
(old)
Goddess of Wisdom
+2

Science and +1

Faith, +1

Faith for every 15

Science per turn.
From that, there are two main considerations for Nuada:
- Nuada's parts that mirror old Commerce actually compare well in isolation. The main issue is that Commerce is slow and expensive for civs that actually have to build roads for city connections, which includes the Celts.
- Nuada only mirrors one part of the old Wisdom. The unconditional yields part was what made Wisdom such a reliable pantheon for the early game, and it is absent in Nuada.
I don't think Nuada needs a rework, I think it just needs to stay true to the early aspects of old Commerce and Wisdom. For instance:
Nuada, the Silver-Handed King
+2
Gold and +1
Science in the city.
+3

Gold from

City Connections.
+1

Culture for every 10

Gold per turn (capped at half the followers in the city), and +1

Golden Age Point for every 5

Science per turn.
+5

Gold from Ceilidh Hall.
It's weird that Rhiannon boosts Ceilidh halls with

GAPs when her pantheon doesn't even give that yield. Should also help boost Rhiannon jut a little, and nerf what could be a very potent new Nuada
I think

GAP makes sense. Rhiannon provides

Culture,

Production and

Gold, the three yields that golden ages boost. You can think of Rhiannon as the pantheon version of a golden age.
On an unrelated note, do the Celts really need to lose faith from cities with only the pantheon after founding? It drops the religious momentum quite hard and makes it quite harder to reform, as your first missionaries take forever to come out.
