Lumra, Bellow of the Woods + Famished Worldsire + Eldrazi Confluence + Salvager of Secrets + Horizon Explorer

Lumra, Bellow of the Woods

Famished Worldsire

Eldrazi Confluence

Salvager of Secrets

Horizon Explorer

How it works

1. Activate any number of lands by tapping them, adding at least 2.
2. Cast Eldrazi Confluence by paying 2, selecting its second mode three times, blinking Lumra, Salvager of Secrets and Famished Worldsire.
3. As Famished Worldsire enters, choose to sacrifice at least the lands tapped for mana in step 1, causing Famished Worldsire to then enter with three +1/+1 counters for each land sacrificed.
4. When Lumra, Salvager of Secrets and Famished Worldsire enter, they each trigger.
5. Resolve the Lumra trigger, causing you to mill four cards and return all land cards from your graveyard to the battlefield untapped due to Horizon Explorer.
6. Resolve the Salvager of Secrets trigger, returning Eldrazi Confluence from your graveyard to your hand.
7. Resolve the Famished Worldsire trigger, causing you to look at some cards from the top of your library and put any land cards from among them onto the battlefield untapped due to Horizon Explorer.
8. Repeat.

This intricate loop revolves around repeatedly resetting your board with Eldrazi Confluence, blinking Lumra, Bellow of the Woods, Salvager of Secrets, and Famished Worldsire all at once. When Lumra and Famished Worldsire re-enter the battlefield, they rapidly pull every land from your graveyard and library, while Horizon Explorer ensures all those lands enter the battlefield untapped and ready to feed Famished Worldsire's devour cost or tap for the mana needed to recast the spell. Meanwhile, Salvager of Secrets conveniently plucks Eldrazi Confluence right back out of your graveyard each iteration, closing the loop to generate infinite mana, landfall triggers, and etb effects.
