Another attempt at a Bringer of the Last Gift Squirming Emergence layout after seeing some reports of a champion Slogurk, the Overslime deck from a Chicago event.
The Slogurk deck focused more on Nissa, Resurgent Animist getting value from the hideout lands that auto-sacrifice and fetch another land. Aftermath Analyst keeps rescuing those lands (and is an elf that Nissa can fetch). Slogurk noms all the land movement. Channel lands like Otawara, Soaring City and Takenuma, Abandoned Mire helps Slogurk invalidate opponent's control cards. Jace, the Perfected Mind is the main finisher.
I'm fitting in Worldsoul's Rage as a second land rescue angle that also can give some interaction against some important threats (like Deep-Cavern Bat). And the Gift Bringer can try to sweep. If the opponent has some threats in the graveyard, maybe Cease / Desist can exile out the worst ones before the Gift sweep hits.
I have Atraxa, Grand Unifier and Titan of Industry as my own graveyard threats. And the Blossoming Tortoise and Founding the Third Path to mill them there. Path and Lier, Disciple of the Drowned can recycle the spells. Likeness Looter can copy any of the pieces that got caught in the graveyard.
Omnath, Locus of All is wild. When Nissa gets rolling, you start getting extra mana that you can't spend, and Omnath lets the mana float into your next turn. The casting cost is crazy, but Nissa can make it happen, and so can the Looter. Omnath counts as an elemental that Nissa can also fetch.
The Buried Treasure seems like perfect ramp on turn 2. You can then play Nissa on turn 3 before playing a land. If that land is a hideout land, Nissa gives you two mana and an elf fetch. Perfect to play an Analyst ready for turn 4 sac. Treasure in the grave counts for Emergence counts and Atraxa card types.
