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 Provisioner 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 loop turns Hearthhull, the Worldseed into a devastating engine by cycling lands directly from your graveyard with Crucible of Worlds. As you sacrifice and replay your lands, Tireless Provisioner floods the board with artifact tokens, its triggers doubled by Virtue of Knowledge's passive Panharmonicon-style effect. Clock of Omens uses those newly minted tokens to constantly untap Hearthhull, letting you repeat the sacrifice-and-draw process while draining your opponents out of the game through Hearthhull's passive life-loss ability.
