Hearthpwn

Draw your cards using the multitude of draw options included.

Play Plated Beetle and kill it.
Play Prelate, and kill it. Do not play it more than once. Buffing it is not needed. 
Play Silver Vanguard and have it die while Undatakah is in your hand.

Now, play Undatakah, and buff it with Sunfury Protector. Every time it is killed from then on, it will give you 3 armor, and play itself again from the graveyard, making an impenetrable wall. 

Silence, polymorph and hex is an obvious weakness of the deck. If Da Undatakah is silenced or either deathrattles is hexed or polymorphed, its over but if he isnt, you can use Augmented Elekk to duplicate him every time hes killed, and from there - barring OTK decks like Mecha`thun or OTK paladin you`re pretty much sure to win.

I have found that shrink raying or equalitying your undatakahs can be a quite effective strategy, as you can kill them off more easily that way.
