Flyers's city

You have to consider to use these cities in specific situations like break a siege and farming favors from enemies. Avoid send them alone without an OLU escort, because if they are the first to hit the city, you'll probably lose all your flyers and you know it takes a lot of time to build a nuke with them.

Best islands for:
harpies - + wood and regular silver or +silver and regular wood
manticores - + wood and regular silver or +silver and regular wood
griffin - + wood and regular silver or +silver and regular wood

Building priorities

Senate 24, in this level you can pick the special constructions;

Academy 31, to unlock temple looting and divine selection;

Farm Max, upgrade farm always, your army power is determined mainly by your farm level; Warehouse 20, to stock resources for conquest, battering ram...;

Market 10, to send resources to other cities;

Barracks 15-25, to build your army faster(use population growth from Hera, you can build your nuke in 2 days, if you have the resources);

Harbor 1, to build anchors(then you can save your flyers when you're offline);

Temple 10-15, it depends of the mythical unit;

Cave 10, to espionage and prevent espionage;

Wall 0-25, it depends of the type of the world;

Resources that one with + max, normal 35, - 30, this is for your army basicly .

Special building: Thermal Baths and Tower/Divine Statue(temple 12), more population and more defense or more favour.

Academy priorities

Don’t research everything!

City guard, when you’re attacked, use your militia, with this research you have more “population” defense;
Meteorology, because your flyers don't need transport boats;

Ceramics, extra 2500 store of resources;

Architecture, you will economize many resources;

Trainer, to build your army faster;

Crane(good if you have the advisors and if you’re active);

Conscription, for cheaper army;

Plow, free farm level basically;
Conquest,...

Temple looting, it allows you to train mythical units much more faster;
Divine selection, phalanx version of the mythcial units.

PS: You should research Phalanx and Battering Ram in Revolt Worlds, if you have resources. So in a revolt, you'll defend better.
