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 Fractured Realm, creating two artifact tokens.
Activate Clock of Omens by tapping the artifact tokens, untapping Hearthhull.
Repeat.
This intricate loop transforms a humble land sacrifice into an engine of endless value by tying together a suite of powerful permanents. While Hearthhull, the Worldseed acts as your primary outlet by sacrificing lands to draw cards and drain life, Clock of Omens untaps it using the artifact tokens generated by Tireless Provisioner's landfall triggers. To ensure you never run out of fuel, Walk-In Closet // Forgotten Cellar lets you continuously replay those sacrificed lands right from your graveyard, all while Mirror Room // Fractured Realm doubles up every single token creation trigger to effortlessly feed the Clock of Omens.
