Activate Hearthhull by paying 1, tapping it and sacrificing a land.
If Hearthhull has eight or more charge counters on it, it triggers, causing each opponent to lose 2 life.
Resolve the Hearthhull ability, causing you to draw two cards and allowing you to play an additional land this turn.
Play the land from your graveyard.
When the land enters the battlefield, Tireless Tracker triggers twice due to Fractured Realm, creating two artifact tokens.
Activate Clock of Omens by tapping the artifact tokens, untapping Hearthhull.
Repeat.
This intricate loop transforms a humble land-sacrificing engine into a devastating victory by turning every land drop into a cascade of resources. At the heart of the setup is Hearthhull, the Worldseed, which turns your sacrificed lands into card draw and life loss for your opponents while gradually growing toward its menacing 8+ stat block. To keep the gears turning, Ramunap Excavator ensures those sacrificed lands never truly stay lost, allowing you to replay them straight from your graveyard turn after turn. Meanwhile, Tireless Tracker capitalizes on each new land arrival by churning out Clue tokens, and the doubling power of Mirror Room // Fractured Realm ensures you get extra artifacts for every single landfall trigger. Finally, Clock of Omens harnesses those newly minted artifacts to tirelessly untap Hearthhull, sealing an endless loop of card draw, artifact entries, and life drain.
