Hearthhull, the Worldseed

Clock of Omens

Toggo, Goblin Weaponsmith

Elesh Norn, Mother of Machines

Perennial Behemoth

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 centers on Hearthhull, the Worldseed as a sacrifice outlet that feeds itself cards and land drops while draining your opponents' life totals once it's fully stationed at eight or more counters. The real magic happens with every land you play from your graveyard using Perennial Behemoth, which triggers Toggo, Goblin Weaponsmith to produce multiple Rock tokens thanks to Elesh Norn, Mother of Machines doubling up those entry triggers. From there, Clock of Omens steps in to utilize those newly minted artifacts, tapping them to untap Hearthhull so the whole loop can begin anew.
