Hearthhull, the Worldseed + Clock of Omens + Tireless Tracker + Crucible of Worlds + Starfield Vocalist

Hearthhull, the Worldseed

Clock of Omens

Tireless Tracker

Crucible of Worlds

Starfield Vocalist

How it works

1. Activate a land by tapping it, adding at least 1.
2. Activate Hearthhull by paying 1, tapping it and sacrificing a land.
3. If Hearthhull has eight or more charge counters on it, it triggers, causing each opponent to lose 2 life.
4. Resolve the Hearthhull ability, causing you to draw two cards and allowing you to play an additional land this turn.
5. Play the land from your graveyard.
6. When the land enters the battlefield, Tireless Tracker triggers twice due to Starfield Vocalist, creating two artifact tokens.
7. Activate Clock of Omens by tapping the artifact tokens, untapping Hearthhull.
8. Repeat.

This elegant engine turns a simple land sacrifice into a devastating loop by letting Hearthhull, the Worldseed fuel its own upkeep; each time you sacrifice a land to draw cards, Crucible of Worlds allows you to immediately replay it from your graveyard. Starfield Vocalist supercharges Tireless Tracker's landfall trigger so that every returned land yields a double bounty of Clues. Those extra artifacts feed Clock of Omens, letting you untap Hearthhull endlessly while Hearthhull's own triggered ability drains your opponents to zero life.
