If you like to be a conjurer like me, summon Daedroths or something equally powerful, like Frost or Storm Atronachs, cast invisibilty on your self and watch the fun. Granted, this is not very glorious, but I'm a mage, not a fighter...
Conjuration is very easy to train, so just keep summoning skeletons until you reach 75 in skill, so you can summon the interesting stuff.
I reached level 100 last night, and summoned the Lich a few times. Those are mean!
Alternatively you can simply use invisibility/chameleon and avoid the Ogres altogether... Even less glorious, but it works...
