Hatred Reborn (Help?)

This is a draft of a deck that is pretty fun to play when it gets rolling. Basically you play aggressive beginning with some ramp, discarding your super big cards especially vorapede, ghoultree, or flayer. keep the offense flowing with strangleroot and emissary especially if you have a deathmantle out. this is rather close to the real life deck i have though i didnt have enough rootbounds or vorapede or beast within so i subbed in the following: 1 forest and 1 mountain for the 2 rootbound, 1 dungrove elder for a beast within, and 1 wurmcoil for a vorapede. I tried playing this on MWS against a hellrider wolfrun deck. I am not sure if he just had better aggro than me or what or just unlucky draws. so please look it over and tell me what you think. Edit: Ideally you are suppose to ultimate in your entire graveyard witht he grimoire, resolve flayer first and BAM! Or roll the die and see if you get Flayer and another with Moldgraf(hopefully saved with a deathmantle)
