I feel like every Uldaros deck will be about the same...but this is interesting. The potential for spells with no mana cost works better than if this were a gyruda clone. The hope for a storm turn also exists. This deck might mill itself for five turns and then win out of nowhere.

The Graveyard is Free Realestate

This is the actual decklist that I own.
Draft the Commanders first from a special pool (in the sideboard) with 4 packs of 10 or 12.
Each commander has partner. If you want to use one of the companions, you can do that as well if you abide by the companion rules and color identity rules. For Umori specifically, you may still have creatures as your commanders as long as the rest of the deck follows its companion rules.
I suggest choosing your commanders (and sometimes a companion) before you've drafted from the main pool. 
Each player automatically gets a command tower and an arcane signet.
Before drafting, players can decide if they want to draft 60 card commander decks or full-sized 100 card decks.
Draft 4 packs of 14 for 60 card decks and 6 or 7 packs of 14 for 100 card decks.
Color Identity does not matter when it comes to lands.
Draft Archetypes:
Reanimator
Cast spell, get value
Freecasting
Theft
Copying spells
Value for targeting your own creatures

My Bad Decklist Thrown Together in a Cave with a Box of Scraps

I realized that the main problem with the last iteration of this Cube was it included white. That pillar was taking a lot of space that could have gone to red and other colors. It seemed to dillute the experience so I made another one without such a useless color.
