Tireless Tracker

Yarok, the Desecrated

Ramunap Excavator

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 Yarok, creating two artifact tokens.
7. Activate Clock of Omens by tapping the artifact tokens, untapping Hearthhull.
8. Repeat.
