Problem with Zhur is that we all get the mana.  Throw in something you could topdeck with X so that you can properly blow your wad all over it.  You don't want to be on the wrong end of Exsanguinate for 10.  Also, what are you putting into your graveyard with Jarad's, and why don't you have some way to get it out onto the battlefield the next turn?

I kind of like this deck, some ramp into deadbridge goliath turn 3 and then sire of insanity turn 4-5 would be cool. the only thing i would suggest would be maindecking 2 disciple of bolas because that guy is tits, especially if you have 7 lands and a skaarg guildmage out (sac a land, gain 4 life, draw 4) or just a pelakka wurm or something. only problem would be that if you draw all those cards with sire out it might be a problem, but I guess you could just sac the sire in that case, and you'll have a hand of 6 cards while all your opponents have 0.
