Eldrazi Spawn Overrun

just as simple straightforward aggro deck. didnt have much room for removal, bolts and such, but this is still very rough, and help would be appreciated. eldrazi monument = win as soon as it comes into play, and so there are 4 of them. awakening zone isnt actually that great, maybe with broodwarden out, and to feed the monument, but still not too good, so i dont run it, something just had to get cut. this deck can run pretty explosive starts, like turn 3 7 7, it just goes turn 2 nest invader, turn 3 brood birthing, sac all 4 for hand of emrakul. yeah, i really should use some removal, and i think awakening zone gets the cut, but it can be pretty nice, so i dont know. i also dont have enough room for hellion eruption. it looks nice, but i would rather have a monument or an overrun slash garruk (still playing around with which one) most of the time. bramblesnap also might get the cut, but it is just so big if you have 3 or more tokens in play, i dont know, i seems nice, so ill keep it for now. i also dont know about how many lands to run. there are huge amounts of ramp, so i will try 22 with 4 temples and see how this works, but i am looking for feedback. and i dont really know what the balance is, and i am too lazy to count, so just assume that the forests and mountains are in the right balance. cards i wanted to run but couldnt fit are bolt, awakening zone, vines of vastwood, growth spasm, bbe, violent outburst, and generally more removal. this deck is practically eldrazi block, if you can replace the overrun and lands, you have block constructed, so that seems good too. no board yet, but coming soon.
