Eloise, Nephalia Sleuth + Ulvenwald Mysteries + Krark-Clan Ironworks + Encroaching Mycosynth

Eloise, Nephalia Sleuth

Ulvenwald Mysteries

Krark-Clan Ironworks

Encroaching Mycosynth

How it works

1. Activate Krark-Clan Ironworks by sacrificing a Clue, adding CC.
2. Eloise and Ulvenwald Mysteries' second abilities trigger.
3. Resolve the Eloise trigger, causing you to surveil 1.
4. Resolve the Ulvenwald Mysteries trigger, creating a 1/1 Human Soldier creature token.
5. Activate Krark-Clan Ironworks by sacrificing the Human Soldier, adding CC.
6. Eloise's first and second abilities trigger.
7. Resolve the first Eloise trigger, creating a Clue artifact token.
8. Resolve the second Eloise trigger, causing you to surveil 1.
9. Repeat.
10. Once you have infinite mana, you may instead sacrifice the Clues to their own abilities.

This loop turns your entire board into an engine of continuous recycling, fueled by the mana-generating power of Krark-Clan Ironworks. Because Encroaching Mycosynth turns all your nonland permanents into artifacts, even your newly minted creatures are valid fodder for the Ironworks. When you sacrifice tokens or creatures, Eloise, Nephalia Sleuth rewards you with card-filtering surveils and Clue generation, while Ulvenwald Mysteries steps in to replace your sacrificed Clues with fresh 1/1 Human Soldier tokens. By cycling these elements back and forth through the Ironworks, you generate infinite colorless mana, infinite sacrifices, and endless looks through your library until you draw into a win condition.
