This is my personal build for a KFT Mill Rogue.
It has the basic spells and fundamental cards of a classic wild mill rogue, but with some extra cards ofthe latest expansion.
In this slow meta, an opponent almost full hand is the joy of any Coldlight Oracle. And with the passive hero power of the Valeera the Hollow , is even more powerful.
The presence of some taunt minions assure you to be safe in the early game, while Sap, Eviscerate and expecially Preparation + Vanish can control even the biggest board.
The Curator is here to provide you a Coldlight Oracle if you don't have it in your hand, also giving you a big priest-proof taunt minion.
Skulking Geist is excellent against Jade Druid, but also can help against token druid, evolve shaman, silence priest and remove some nasty shield slam and whirlwind. 
The Shadowblade can help you remove some nasty minion or even save yourself from fatique in a decisive turn.
Prince Valanar can assure you defense and, with his lifesteal,it will keep you alive with the help of the good ol' Earthen Ring Farseer.
Nat, the Darkfisher is a card that you want to play after a Vanish or a Doomsayer with the passive hero power of valeera. One darkfisher is meh. Two darkfishers with the opponents hand full is a whole different thing.
I've been playing this deck for days, and it suffers only with fast aggressive decks, and a little bit with the recent DK Control Warrior.
Let me know what you think! ^_-

SUBSTITUTION:
If you don't have Prince Valanar remove also the Stonehill Defender and add two Saronite Chain Gang
If you don't ave Nat, the Darkfisher add one Youthful Brewmaster
