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 Virtue of Knowledge, creating two artifact tokens.
Activate Clock of Omens by tapping the artifact tokens, untapping Hearthhull.
Repeat.
This intricate engine uses Hearthhull, the Worldseed as a sacrifice outlet to draw cards and drain your opponents, while Crucible of Worlds ensures the sacrificed lands never truly leave your graveyard. As you replay those lands, Eusocial Engineering generates robot tokens, and Virtue of Knowledge doubles those landfall triggers to yield an army of artifacts. Clock of Omens then uses those freshly minted tokens to untap Hearthhull, resetting the entire loop so you can draw your deck and grind down the table.
