Hearthhull, the Worldseed

Clock of Omens

Eusocial Engineering

Yarok, the Desecrated

Conduit of Worlds

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, Eusocial Engineering triggers twice due to Yarok, creating two artifact tokens.
7. Activate Clock of Omens by tapping the artifact tokens, untapping Hearthhull.
8. Repeat.

This ingenious engine transforms Hearthhull, the Worldseed into an unstoppable land-sacrificing powerhouse by feeding it lands straight out of your graveyard with Conduit of Worlds. Every time you activate Hearthhull's ability to draw cards and drop an extra land, Eusocial Engineering leaps into action, doubling its Robot token generation courtesy of Yarok, the Desecrated's static doubling effect. Those fresh tokens immediately fuel Clock of Omens, tapping themselves to untap Hearthhull so you can repeat the whole vicious cycle. As the lands endlessly cycle between the battlefield and the graveyard, Hearthhull's stat-boosting charge counters pile up until it transforms into an 8+ flyer, draining your opponents dry with every sacrificed land.
