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 ingenious engine begins by tapping a land for mana and sacrificing it to activate Hearthhull, the Worldseed, which draws you two cards, lets you play an extra land, and fires off a drain trigger if it has reached eight charge counters. Perennial Behemoth then steps in to let you replay that sacrificed land directly from your graveyard. When the land enters, Eusocial Engineering triggers to generate a pair of robot tokens, a creation doubled by Virtue of Knowledge's static replacement effect. Finally, Clock of Omens uses those two fresh tokens to untap Hearthhull, allowing you to cycle the whole loop again for infinite card draw, life loss, and land drops.
