Lumra, Bellow of the Woods + Squandered Resources + Eldrazi Displacer

Lumra, Bellow of the Woods

Squandered Resources

Eldrazi Displacer

How it works

1. Activate Squandered Resources by sacrificing a mana-producing land, adding one mana of any type that land can produce.
2. Repeat step 1 at least two more times, and more times if desired, ensuring to leave at least one land on the battlefield.
3. Activate Eldrazi Displacer by paying 2C, blinking Lumra.
4. When Lumra enters the battlefield, it triggers, causing you to mill four cards and then return all land cards from your graveyard to the battlefield tapped.
5. Repeat.

This loop transforms the natural synergy of lands and mana into a self-sustaining engine, starting with Squandered Resources converting your real estate into the exact fuel you need. You feed that mana into Eldrazi Displacer to repeatedly exile and recast Lumra, Bellow of the Woods, whose grand entrance mills your library and immediately brings every single land back from the graveyard onto the battlefield tapped. Each time Lumra enters anew, you simply sacrifice those freshly returned lands to Squandered Resources to pay for Eldrazi Displacer's activation again, netting infinite mana of any type your lands can produce along the way.
