The newest build from my warped mind is the Cultist of whom...would actually fit in better in Oblivion...but that is not the point.

Cultist
Race:Any (What Daedra you serve may determine this)
Skill Trees: Speech, Sneak, Destruction, Conjuration, Enchanting (Optional)
RP Items: Mythic Dawn Robes/Vaermina Priest Robes/Hooded Monk Robes, Daedric Artifacts
Stone: Any
Shout: Any
Variations: Mythic Dawn Cultist (1H, Smithing), Nocturnal Cult/Nightingale (Pickpocket, Archery), etc (The prince determines the style)
Discussion: The purpose of this build is to suit a certain Daedric RP need that does not involve being a hulking Daedric armored tank. Use Conjuration and a Follower to give the illusion that your cult holds many. Get as many Artifacts as you can but try to use your cult's item primarily. For me this Build is inspired greatly by Warhammer 40k and so my personal Cultist reflects a Servant of Tzeentch but to each their own eh?

Note: I always stress that these builds are best played with RP in mind. Comments?
