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 Fractured Realm, creating two artifact tokens.
Activate Clock of Omens by tapping the artifact tokens, untapping Hearthhull.
Repeat.
This intricate loop centers around Hearthhull, the Worldseed, which lets you sacrifice a land to draw cards and fund your engine once it hits eight charge counters. To feed this sacrifice habit without running dry, Icetill Explorer steps in to let you replay those sacrificed lands right back out of your graveyard. Every time a land drops, Eusocial Engineering triggers to generate artifact creature tokens, doubling its output thanks to the passive duplication power of Mirror Room // Fractured Realm. Finally, Clock of Omens harnesses those freshly minted tokens by tapping them to untap Hearthhull, allowing you to cycle through the entire sequence indefinitely while draining your opponents' life totals.
