Hearthhull, the Worldseed

Clock of Omens

Tireless Tracker

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 Tracker 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 your land drops into a devastating storm of life loss and card draw by looping a single sacrificed land. Hearthhull, the Worldseed acts as the primary outlet, letting you sacrifice a land to draw cards while draining your opponents once it's fully awakened with charge counters, while Crucible of Worlds ensures that same land can be immediately replayed from your graveyard. Tireless Tracker feeds the loop by producing Clue tokens upon land entry—doubled delightfully by Yarok, the Desecrated's static ability—which are then tapped alongside Clock of Omens to untap Hearthhull, readying the spacecraft to repeat the cycle indefinitely.
