Lumra, Bellow of the Woods + Famished Worldsire + Eldrazi Confluence + Skullwinder + Archelos, Lagoon Mystic

Lumra, Bellow of the Woods

Famished Worldsire

Eldrazi Confluence

Skullwinder

Archelos, Lagoon Mystic

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, Skullwinder 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, Skullwinder 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 Archelos.
6. Resolve the Skullwinder 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 Archelos.
8. Repeat.

This intricate loop relies on constantly recycling Eldrazi Confluence to repeatedly blink your entire engine, fueled by the lands you sacrifice and recover. Each iteration uses Eldrazi Confluence's second mode to reset Lumra, Bellow of the Woods, Skullwinder, and Famished Worldsire, which together mill your deck, pull Eldrazi Confluence back to your hand, and dig deep for more lands. Meanwhile, Archelos, Lagoon Mystic ensures all those returning lands and permanents enter untapped, allowing Famished Worldsire to safely devour them for massive power boosts without stalling your mana production.
