Hearthhull, the Worldseed

Clock of Omens

Toggo, Goblin Weaponsmith

Elesh Norn, Mother of Machines

Icetill Explorer

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, Toggo 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 intricate engine relies on Hearthhull, the Worldseed as a sac-outlet that draws you cards and drains your opponents when fueled by land sacrifices, while Icetill Explorer ensures those sacrificed lands can simply be replayed straight from your graveyard. Toggo, Goblin Weaponsmith converts every single land drop into Rock tokens, which Elesh Norn, Mother of Machines doubles to effortlessly feed Clock of Omens; by tapping those generated Rocks to untap Hearthhull, you bypass the spacecraft's activation limits and sustain the loop indefinitely.
