It Depends on what God your opponent is
if Against Norse...i would go Ptah+Sekhemut(or Hathor) depends if u want uber Slingers or chariots or if u want Petsuchos and uber buildings, but Against norse i would rely mostly on Barracks units...only time to Make Camels against Norse is if they are making Jarls...any other wise Stick to Spear+Sling or Axe+Sling backed bye Wadjets/Petsuchos and Siege Cheese and Mercs(Sekhemut boosts siege towers and gives u scrabs) where as Hathor gives u Sun-Dried-Mudbrick making all buildings Stronger and Cheaper
Against Greek...i would prolly Fast Herioc with Ra...as Greek units in classical are too superior to Eggy Barrack units and will run u over later in Classical to mid Heroic...u gotta take Advantage of Ra's uber Camels+Chariots against Greek...against Greek i prefer to meatgrind a Greek Opponent with a Camel+Chariot combo with a few Axemen or Spearmen Mixed in..Chariots really Maul Prodromos if u micro them...and Camels really Own Peltasts...this is Greeks Best answer for the Camel Chariot combo...if the Greek player gos Hoplite+Hippikon...it gets a little tougher...thas where Axemen and Petsuchos come into play...Ra Camels do okay against Prodromos...but a Ra Camel+Chariot combo microed Properly will beat a Herioc age Greek Hard counter combo of the Prodromos+Peltast..remeber...chariots have more range then Peltast...this suits your advantage as your chariots will kill his prodromos faster then his peltast can kill your Chariots...just make sure u have enough preists to deal with the Hydra's/Nemean lions/Manicores i would Advance Bast+Hathor against Greek...get 3 or 4 Petsuchos to go with your camel+Chariot combo then cast eclipse for total ownage
Against Atlantean-i would go for a 2 Barracks "brisk" herioc age...trying to fight Atlantean in Classical just doesn't work...Cherio's murder Spears hardcore...when Ra gets to Herioc though..the Camel+Chariot+Petsuchos and Axemen Combo is the way to go...or u can be more Pop Freindly and go Camel+Axemen...Axemen mop the floor with Katapeltes and Camels Own Turma Contarious Arcus and Cherio...again i would go Bast+Hathor against Atlantean and mass Petsuchois and cast Eclipse
Against Another Egypt is totally bye choice...u can go Ptah+Sekhemut+Horus and grind it with Barracks units or u can go Bast+Sekhemut+Osiris and over-power them with superior Camels and Chariots...depends on your playing style
as on God Choices...Sekhemut is very good too Against Atlantean...as Atlantean has weak buildings and Sekhemut boost the Siege and gives u Scrabs...Scrabs are hard for Atlanteans to counter cuz of the cost of their Hero's after they run out of Valor....
on the Ptah.vs.Bast...well it depends...i personally Prefer Bast belive it or not...Ptah gives cheaper farms...but...Bast gives u a better econ over all...i was testing my FH and i get a "MUCH" better econ with Bast over Ptah...u need "less" farmers to get the same amount of food with Bast's Sacred Cats and Plow then u do with Ptah's Shaduf+Plow...u end up spending roughl;y the same in costs...cuz Bast Myth Farming tech and the other econ techs means u need "less" farmers to get the same output...which means u can stack more villes on gold for Merc spamming, and more on wood for siege Cheese...Bast Econ techs have been "Fixed" and they really up Ra's Econ
Sekhemut.vs.Hathor-now this 1 is even...and depends on the opponent...Hathor is good against everyone especially greek and Atlantean...due to Sun-Dried-Mudbrick cheaper and Stronger buildings makes it easier to expand and take those TC and your buildings will Stand up longer and Locust swarm will destroy their Farms and the Merc Techs really increse the lifespan of Mercs. But Sekhemut has her Advantages to..Bone bow makes Chariots uber, Citadel adds the 10 pop u need for those pop consuming Migdol units, and Slings of the Sun makes slingers a Cheap alternative to chariots and the Scarab+The Siege Techs give Sekhemut the best Siege in the game...so it depends on your Strategy really...but the Free Scarab can help u take down a forward building eary on which can help your expansion
Osiris.vs.Horus-Depends...if u have been using primarily Barracks units go Horus...if u been grinind with Migdol units go Osiris..Osiris is also good for getting Titan out quickly...Desert Wind makes Ra Camels amazing, and the New Kingdom Improvement..really boosts Ra's Mythic Econ as 1 Pharoah can empower farming and the other on the Market...give u the Resources to pump those Migdol units...and mummys are good for Stealing opponents strong myth units like Hega gigantes and Collusus..Horus is good on "low gold" maps...as he beniftis cheapest unit, Avengers only cost food and favor, and his tornado can take out a titan gate if properly place with some luck on your side...
it just depends on the map...and what strategy u are trying to implement and against what other major god
