Hearthhull, the Worldseed + Clock of Omens + Tireless Provisioner + Ramunap Excavator + Starfield Vocalist

Hearthhull, the Worldseed

Clock of Omens

Tireless Provisioner

Ramunap Excavator

Starfield Vocalist

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 Starfield Vocalist, creating two artifact tokens.
7. Activate Clock of Omens by tapping the artifact tokens, untapping Hearthhull.
8. Repeat.

This clever loop turns Hearthhull, the Worldseed into an unstoppable engine of attrition once it hits its eight-counter awakening, using its own activated ability to cycle through your lands while draining the table dry. The engine is infinitely fueled from the graveyard thanks to Ramunap Excavator letting you replay your sacrificed lands, while Tireless Provisioner churns out artifact tokens on every landfall. Thanks to Starfield Vocalist doubling those landfall triggers, you produce an excess of artifacts to feed directly into Clock of Omens, which untaps Hearthhull to keep the sacrifice-and-draw cycle spinning indefinitely.
