GU Eldrazi Ramp

Let's start:

Turn 2: Warping Wail/ Rattleclaw Mystic/ Leaf Gilder




On turn 3, We can cast a Thought-Knot Seer for hand disruption and early attacking. Maybe we can cast Kiora.



Other ramp cards:

Nissa's Pilgrimage, Map the Wastes, Sylvan Scrying, Shrine of the Forsaken Gods, Oblivion Sower, Nissa's Renewal


Finishers:

Hangarback Walker - It combos with Kiora, Master of the Depths.
Ulamog, the Ceaseless Hunger - Exiling 2 permanents is good to race over Abzan.
Ugin, the Spirit Dragon - it's the best removal for Ramp decks

Crush of Tentacles(I like this card but the meta is full of Rhinos and Den Protecters, it can't be in tier 1 decks),
Sphinx of the Final Word( Building up mana into Sphinx with creatures can evade Crackling Doom and Foul-Tongue Invocation. A Stubborn Denial would be great to counter Crux of Fate)


Others:


Sideboards:
Versus Esper control: Rending Volley, Gaea's Revenge, Whisperwood Elemental
Versus Tokens: Kozilek's Return


The list:

 18 Creatures
3     Hangarback Walker
4     Sylvan Advocate
4     Drowner of Hope
4     World Breaker
3     Ulamog, the Ceaseless Hunger
 17 other spells
2     Part the Waterveil   
2     Warping Wail   
2     Kiora, Master of the Depths
4     Nissa's Pilgrimage    
4     Explosive Vegetation    
3     Ugin, the Spirit Dragon
 25 Lands
9     Forest        
5     Island        
4     Lumbering Falls        
3     Sanctum of Ugin        
4     Shrine of the Forsaken Gods

Plan B:
Beside casting Ulamog and Ugin, we can search for lands to optimize Nissa, Vastwood Seer and Sylvan Advocate - all make Stubborn Denial ready to counter removals.
