Unholy Warlord
Normal speed makes speed even more crucial therefore rush is even more potent. War takes as much turns as on epic, but research, production and war weariness are faster. Rushing with 2-move units is less effective on marathon since you have time there.
Someone posted a deity game few months ago (Snaaty?) here which ended in carefully done Cavarly rush on normal. War lasted about 10 turns. That game changed my style of play. Obsolete in his WE games also made his first war with cavarly alone I believe.
Are you referring to this playthrough by Rusten? That was a pretty damn impressive game.
