Hearthhull, the Worldseed

Clock of Omens

Tireless Provisioner

Yarok, the Desecrated

Crucible of Worlds

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, Tireless Provisioner triggers twice due to Yarok, creating two artifact tokens.
7. Activate Clock of Omens by tapping the artifact tokens, untapping Hearthhull.
8. Repeat.

This intricate engine turns the natural cycle of land destruction and rebirth into a devastating loop, anchored by Crucible of Worlds which lets you continually replay lands straight from your graveyard. Each time a land re-enters, Tireless Provisioner triggers twice thanks to Yarok, the Desecrated, flooding your board with a pair of artifact tokens. Those tokens feed directly into Clock of Omens, letting you untap Hearthhull, the Worldseed so you can pay its cost and sacrifice another land to draw cards and drain your opponents' life totals once it's fully charged.
