The game plan is easy , Bring Ulamog, the Ceaseless Hunger to the battlefield !
In order to do that , you need 10 mana , it's a lot and it may take a lot of turns ... but let's use the power of sacrifice instead !
Each Eldrazi scion is equal to 1 mana , and , thanks to From Beyond , one of our key cards , we are able to have 1 every turn , Scions can also be used to gain time as defense
We will start slow with some Blisterpod and Carrier Thrall to defend ourself
They still have and utility later , they can be sacrificed twice !
Now why do we sacrifice ?
To have awesome game changing effects !
Catacomb Sifter let you scry 1 every time one of your creatures dies , it's weak ?Coupled with Smothering Abomination , it's an awesome combo that's let you scry 1 + draw every turn (Warning : This one only work with sacrifice and not only with yours creatures dying )
Add to this a Rot Shambler who will gain +1/+1 every turn and you got a really strong combo there
Also
Brood Butcher
let you kill "unkillable" creatures by attacking them with -2/-2
Now the best part , when you will have enough sions , just sacrifice a From Beyond (There is 4 in the deck , you will have one almost every games) to bring Ulamog, the Ceaseless Hunger into your hand !
Then you almost already won , when Ulamog, the Ceaseless Hunger enter the Battlefield , exile whatever you want , if you're able to cast it really early in the game , don't hesitate and exile lands , this way , you will be far ahead and as you only need 3 turn to win thanks to Ulamog, the Ceaseless Hunger effect , its almost already won.
