This is an attempt at an Eldrazi Ramp, while remaining colorless.
Land Analysis
It definitely relies on dropping an Eldrazi Temple and Wastes. Sanctum of Ugin can be placed early but is good for retrieving lost creatures later. Tron combo with Expedition Map is surefire good mana.
Creatures Analysis
Basically, try to get down a Conduit of Ruin and throw down the 7+ creatures to help out, like Void Winnower for counter or get Emrakul, the Aeons Torn in your hand to throw him down next turn. If you fear your Conduit is going to die, get out an Artisan of Kozilek and pull him back out when you want to, thus using Conduits effect twice! You're priority is Emrakul but Ulamog, the Ceaseless Hunger is a fantastic backup that can also make it pretty darn difficult for an opponent to recoup their losses.
Instants/Sorceries
Not a lot to say here. Warping Wail I included for cards like Appetite for Brains but it's also just a 2 CMC counter spell with the ability to add mana. Not of This World because once you have some of the "not uncounterable Emrakul" big boys down, you want to keep them there. Titan's Presence for board clear, I'd try to save it for what Conduit can't block effectively.
Artifacts
Quicksilver Amulet for surprise creatures and Everflowing Chalice if we want a source of mana. Best case scenario is having a tron down and a quicksilver so you can put just about any creature on the field, due to your large mana pool you'll most likely end up using leftover mana to draw cards or feed it into more quicksilver casts. This has presented a possibility of a turn 3 Emrakul. Expedition Map lets us fill out Tron early or put in more Eldrazi Temple or Sanctum of Ugin. Arcane Encyclopedia or Mind's Eye for some draw power. I throw in Mind's Eye since it's only 1 mana to get a card and lets you match draw power with opponent, but it's more expensive. Arcane Encyclopedia is less money but eats 3 mana each turn for a card.
Weakness: Bad hand and a highly preemptive burn/counter deck. You can only counter sorceries early game and your defense may take a turn or two to come out. Also, any form of land wipe could set you back and basically ruin your chances, but those may fall under Warping Wail and I put in the Chalice specifically for a source of mana that isn't lands in case someone has land removal.
This deck can be made a little more budget if you add someone other than Emrakul, the Aeons Torn or you can just rely on Pathrazer of Ulamog.
I don't know TappedOut very well, so I'm constantly editing the deck for the sake of playtest and may not edit the description to adjust to my adjustments until after a short break.
