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 loop turns Hearthhull, the Worldseed into an insatiable engine by feeding its land-sacrificing activation directly back into your hand and battlefield. The sac-and-draw ability provides the land you need to play, which Conduit of Worlds lets you seamlessly replay right out of your graveyard. Every time that land hits the board, Tireless Provisioner triggers twice thanks to Virtue of Knowledge's doubling effect, showering you in artifact tokens. Those tokens serve as the fuel for Clock of Omens to untap Hearthhull, resetting the cycle while draining your opponents dry through Hearthhull's own triggered ability.
