I think it's another of my famous (hard to beat, but hard to win with) designs. Design philosophy - naturally, everything revolves around what you're fighting, but you've got the Sherdan to smash through the enemy foot (hopefully) and the Chariotry to shoot up the rest of their army while this is in progress. The Egyptian foot is only there as a pseudo light infantry. You've got to have them, and they are only 120 points, so can act as rear support or go into rough terrain to give some light foot a hard time (hopefully).
I really am sure that this is a comp laughing stock, but it might be fun.
Tell me what you think... however if you're going to say something please back it up with 'I'd take x and get rid of y'. There is no much point in saying 'Egyptian infantry in 8's would be better... because I'd have to find the points for that, so by building them up to 8's would reduce something else (probably the Sherdan, which are designed to make it harder to disrupt with shooting by being in 10s).
