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, Eusocial Engineering triggers twice due to Elesh Norn, creating two artifact tokens.
Activate Clock of Omens by tapping the artifact tokens, untapping Hearthhull.
Repeat.
This intricate loop transforms a humble land sacrifice into an engine of relentless destruction, fueled by Hearthhull, the Worldseed's ability to turn sacrificed land into card draw and life loss. Every piece serves a vital purpose: Eusocial Engineering provides a steady stream of artifact fodder with its landfall ability, which Elesh Norn, Mother of Machines doubles to churn out two Robot tokens instead of one. Those fresh tokens immediately feed Clock of Omens, allowing you to untap Hearthhull so it can be activated again, while Conduit of Worlds ensures the sacrificed lands never truly stay gone by letting you play them straight from your graveyard.
