Hearthhull, the Worldseed + Clock of Omens + Tireless Provisioner + Yarok, the Desecrated + Ramunap Excavator

Hearthhull, the Worldseed

Clock of Omens

Tireless Provisioner

Yarok, the Desecrated

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, 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 setup turns land-sacrificing into a self-sustaining engine by transforming Hearthhull, the Worldseed into an active sacrifice outlet that feeds you card draw. To fuel the loop continuously, Ramunap Excavator lets you immediately replay the sacrificed land from your graveyard, while Tireless Provisioner ensures that every re-entry spits out artifact tokens doubly capitalized by Yarok, the Desecrated's doubling clause. Clock of Omens then acts as the ultimate mechanical bridge, utilizing those freshly generated artifacts to untap Hearthhull so you can repeat the process indefinitely.
