My response to a 'Phalanx Noob Box' would be to set my own army up in proper historical formation, well out out of his missile range, on good terrain, and then just sit and wait. Wait him out. If he's a noob, he'll get bored waiting and attack - and he has to mess up his Noob Box formation to do that.
Otherwise nothing happens, there's no battle, and the match is a draw. All very historical, ancient armies often faced each other for days on end without fighting while each side waited for an advantage to appear.
