Oh, I don't know about that.... I prefer a lot more archers, like Pharoah's Bowmen, and that with Egyptians' elite phalanx unit, rather than just 2.
And the army composition comes out to be this:
1 General (Assuming you buy one), 4 Cav, 2 Archer, 1 onager and
12 Phalanx Units. This makes for a very rigid formation, and as many multiplayer games have cwb rules, the enemy can utilize a lot more cavalry than your plan calls for (So your nice Sacred Band Cav will be overrun by 8 Cataphract Units
).
I would personally use an army composition like this:
1 Armored General (or give my general gold ups in armor), 6-8 Cav, 4 archers, and 7 pike units (I need the extra numbers, as pikemen have more men than hoplite units per unit card).
This allows you to overrun the enemy cav (hopefully), and counter-attack any enemy archers. And because I specifically use Pikemen, (And esp. if my enemy is using hoplites), hopefully, I'll have enough men to make up for my lack of unit cards (ie. 7 to 12).
