Kodama of the East Tree

Petrified Field

Echoing Deeps

Field of the Dead

Horizon Explorer

How it works

1. Play Petrified Field.
2. When Petrified Field enters the battlefield, Kodama of the East Tree and Field of the Dead trigger.
3. Resolve the Kodama of the East Tree trigger, putting nothing onto the battlefield.
4. Holding priority, activate Petrified Field's second ability by tapping and sacrificing it, returning Echoing Deeps from your graveyard to your hand.
5. Resolve the Field of the Dead trigger, creating a token.
6. When the token enters the battlefield, Kodama of the East Tree triggers, putting Echoing Deeps from your hand onto the battlefield untapped as a copy of Petrified Field.
7. When Echoing Deeps enters the battlefield, Field of the Dead triggers.
8. Holding priority, activate Echoing Deeps using Petrified Field's second ability by tapping and sacrificing it, returning Petrified Field from your graveyard to your hand.
9. Resolve the Field of the Dead trigger, creating a token.
10. When the token enters the battlefield, Kodama of the East Tree triggers, putting Petrified Field from your hand onto the battlefield.
11. When Petrified Field enters the battlefield, Field of the Dead triggers.
12. Repeat from step 4.

This ingenious loop relies on a self-sustaining cycle of land recursion and triggers, fueled entirely by Kodama of the East Tree and Field of the Dead working in tandem. As you cycle Petrified Field and Echoing Deeps back and forth between the battlefield and your graveyard, Horizon Explorer ensures that every land enters the battlefield untapped to keep the chain moving seamlessly. Every iteration leverages the lands entering to churn out an endless horde of Zombie tokens, turning a simple land drop into an infinite loop of landfall triggers and creature generation.
