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 Yarok, creating two artifact tokens.
Activate Clock of Omens by tapping the artifact tokens, untapping Hearthhull.
Repeat.
By sacrificing lands to fuel Hearthhull, the Worldseed's card-drawing activation, you simultaneously trigger its drain ability and enable Crucible of Worlds to seamlessly replay those very lands from your graveyard. The newly entering lands feed Eusocial Engineering, whose landfall triggers are doubled by Yarok, the Desecrated to flood your board with Robot tokens. Finally, Clock of Omens harnesses those newly created tokens to untap Hearthhull, the Worldseed, creating a self-sustaining loop that continuously draws cards, drains your opponents, and generates an endless supply of artifacts.
