Golos Gates (EDH / Commander)

Emergent Ultimatum Pile 1:
Reshape the Earth, Dark Petition, Rude Awakening
If keep Reshape the Earth and Rude Awakening: Find remaining Gates and Maze's End, untap with Rude Awakening, activate Maze's End to win
If keep Reshape the Earth and Dark Petition: Search for Rude Awakening, hit the combo. Requires 1G in addition to Ultimatum cost (9 lands)
If keep Rude Awakening and Dark Petition: Search for Seeds of Renewal, untap all lands, cast Seeds, pick up Dark Petition and Rude Awakening, search for Scapeshift, cast Scapeshift, untap lands, activate Maze's End. Requires 10 lands to ensure 10 gates, but also 10 untapped lands are required to afford the full combo (float 3 mana before resolving first Rude Awakening).

Emergent Ultimatum Pile 2:
Scapeshift, Dark Petition, Rude Awakening
As above, requiring 10 lands minimum.

Emergent Ultimatum Pile 3:
Reshape the Earth, Diabolic Tutor, Rude Awakening
As above, but requires 12 due to a lack of ritual mana from the tutor.

Emergent Ultimatum Pile 4:
Scapeshift, Diabolic Tutor, Rude Awakening
Exactly as above, requiring 12 lands minimum.

Emergent Ultimatum Pile 5:
Seasons Past, Diabolic Tutor, Rude Awakening
If keep Seasons Past, Diabolic Tutor: Search Rude Awakening, Seasons Past to pick up Diabolic Tutor. Cast Rude Awakening, untap all lands, cast Diabolic Tutor, find Seasons Past, pick up Rude Awakening and Diabolic Tutor. Requires 16 lands to make infinite mana.
If keep Rude Awakening, Diabolic Tutor: Search Seasons Past, untap all lands, cast Seasons Past and pick up Rude Awakening and Diabolic Tutor. Again, requires 16 lands to make infinite mana.
If keep Seasons Past, Rude Awakening: Untap all lands, pick up Rude Awakening and whatever other value is in the yard. Lots of weird iterations to go infinite from here, but it depends on the graveyard.

Emergent Ultimatum Pile 6:
Seasons Past, Mystical Tutor, Rude Awakening
As above, but requires a cantrip (Explore, Growth Spiral, Scale the Heights, Lonely Sandbar, or Tranquil Thicket) in hand. Reduces the number of lands necessary to go infinite by 1-2, depending on the exact cantrip.
