Hearthhull, the Worldseed

Clock of Omens

Eusocial Engineering

Elesh Norn, Mother of Machines

Ramunap Excavator

How it works

1. Activate a land by tapping it, adding at least 1.
2. Activate Hearthhull by paying 1, tapping it and sacrificing a land.
3. If Hearthhull has eight or more charge counters on it, it triggers, causing each opponent to lose 2 life.
4. Resolve the Hearthhull ability, causing you to draw two cards and allowing you to play an additional land this turn.
5. Play the land from your graveyard.
6. When the land enters the battlefield, Eusocial Engineering triggers twice due to Elesh Norn, creating two artifact tokens.
7. Activate Clock of Omens by tapping the artifact tokens, untapping Hearthhull.
8. Repeat.

This engine sets up an infinite loop of sacrifice and resurrection by cycling your lands right back into play. With Ramunap Excavator allowing you to play lands directly from your graveyard, you can continually feed a land to Hearthhull, the Worldseed's ability to draw cards and keep your land drops flowing. Each time that land returns, Eusocial Engineering triggers to generate a pair of Robot tokens, an effect doubled by Elesh Norn, Mother of Machines for maximum token output. Those newly minted artifacts then serve as fuel for Clock of Omens, letting you untap Hearthhull endlessly so you can repeat the sacrifice. As the loop spins out of control, Hearthhull's static drain ability triggers repeatedly from the sacrificed lands to bleed your opponents out of the game.
