It really depends on your playstyle and the map. I rush culture early game so getting mysticism is not a great delay. In my current game with Seondeok I've gone Craftmanship, State Workforce, Gov. Plaza, 2x Pingala in capital (culture), Foreign Trade, Mysticism, Early Empire, begin Oracle in capital, Political Philosophy. Then finished Oracle with a chop with Autocracy bonus and went for Ancestral Hall. It's all about the timing, I reached Political Philosophy on turn 49 with no culture city state nor even boost from meeting 3 city states, just settled a coffee for a +1 culture. In conclusion, 6 Great Scientist Points and PP on turn 49. As soon as capital reaches pop 7, go for theatre square and 6 Great Writer Points as well. On turn 60 or so I finished Ancestral Hall and went for Recorded History for the 4th governor title. It went to Magnus, that finished the Pyramids in my second city. Then I transferred him to capital and with 5th governor title from Defensive tactics spammed like 6 - 7 settlers from turn 70 to 85. All cities began with 6 charge builders.
