Double Masters

Sorcery

Return target creature card from your graveyard to the battlefield.
Flashback—Sacrifice three creatures. (You may cast this card from your graveyard for its flashback cost. Then exile it.)

Dread Return

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

Gather ’round, scallywags, and listen to the tale of a vessel cursed by the dark moon.
This deck commands the Black Pearl herself, steered by two doomed souls. At the helm stands the Ghost of Ramirez DePietro, a phantom captain slipping through enemy lines like fog. Every time he strikes from the shadows, he plunders the abyss of your graveyard, smuggling lost cards back into your hand.
But a phantom needs a curse to bind his crew. Enter Tormod, the Desecrator, the literal embodiment of the Aztec curse. The moment Ramirez—or any dark ritual—reclaims a card from Davy Jones’ locker, the curse snaps tight. For every soul disturbed in the depths, Tormod commands an endless army of undead skeleton tokens to rise onto your battlefield.
You’ll hoard a king’s ransom in Treasure gold to fuel this unholy cycle of death and resurrection. Hoist the colors, step into the moonlight, and show the table that the crew of the Black Pearl never stays dead! 

Curse Of the Black Pearl

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
