Crazy quick manaramp with massive Eldrazi Spawns.
The Focus of this deck is using Eldrazi Spawn to get either quick mana or make them super powerful, until you can get Emrakul, the Aeons Torn out.
Hit the ground running with Spells like Brood Birthing, Everflowing Chalice, and Awakening Zone to get some quick eldrazi spawns out. As soon as you can, play Emrakul's Hatcher. Then, attach the Aura Splinter Twin on him. Then abuse the hell out of his new tap ability.
Every turn, tap Emrakul to make a copy of him and get 3 more spawns. Once you get this combo going, start pulling out Broodwardens and Eldrazi Monument. 1 Broodwarden makes your army of spawns all 2/2 each if you have 1 out, 4/3 for 2, 6/4 for 3, and 8/5 for 4 Broodwardens. Eldrazi Monument gives all of your creatures +1/+1, flying, and indestructible. Every upkeep you have to sacrifice a creature though. Just sacrifice 1 spawn and tap Emrakul for more.
Then, once you've got a little army going, start pulling out bigger hitters. Use Skittering Invasion to get even more spawn tokens, and use them to play Pathrazer of Ulamog or Spawnsire of Ulamog. Pathrazer with indestructible and flying, he's gonna WIPE their field no problem. With Spawnsire however, you want to use his 4 mana to build up more and more eldrazi spawn tokens, until you can pay the 20 mana ability. Pull out ALL of your Pathrazers, Spawnsires, and your 1 Emrakul, the Aeons Torn onto the field. Once you get the 20 ability activated, it's game over.
Another option is to get your Garruk out on the field. He can untap your lands for even more mana. Once you get his -4 ready, give your army of flying, indestructible eldrazi spawn tokens +3/+3 and trample. What a hilarious way to die, death by Eldrazi spawns.
