Kodama of the East Tree

Petrified Field

Echoing Deeps

Amulet of Vigor

Thranduil the Strategist

How it works

1. Play Petrified Field.
2. When Petrified Field enters the battlefield, Kodama of the East Tree and Thranduil the Strategist 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 Thranduil the Strategist 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 as a copy of Petrified Field.
7. When Echoing Deeps enters the battlefield, Thranduil the Strategist and Amulet of Vigor trigger.
8. Resolve the Amulet of Vigor trigger, untapping Echoing Deeps.
9. 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.
10. Resolve the Thranduil the Strategist trigger, creating a token.
11. When the token enters the battlefield, Kodama of the East Tree triggers, putting Petrified Field from your hand onto the battlefield.
12. When Petrified Field enters the battlefield, Thranduil the Strategist triggers.
13. Repeat from step 4.

This elegant loop leverages Kodama of the East Tree as a mana-value-matching engine that constantly recycles your lands, turning every land drop into a cascade of triggers. As you alternate playing Petrified Field and Echoing Deeps, Amulet of Vigor ensures those copied lands enter ready to immediately sacrifice themselves back to your hand. Meanwhile, Thranduil the Strategist provides the crucial landfall catalyst, flooding the board with Elf tokens that satisfy Kodama's entry condition to keep the whole machine spinning.
