Kodama of the East Tree + Dimir Aqueduct + Thranduil the Strategist

Kodama of the East Tree

Dimir Aqueduct

Thranduil the Strategist

How it works

1. Play Dimir Aqueduct.
2. When Dimir Aqueduct enters the battlefield, it, Thranduil the Strategist, and Kodama of the East Tree trigger.
3. Resolve the Kodama of the East Tree trigger, choosing not to put anything from your hand onto the battlefield.
4. Resolve the Dimir Aqueduct trigger, returning it from the battlefield 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 Dimir Aqueduct from your hand onto the battlefield.
7. When Dimir Aqueduct enters the battlefield, it and Thranduil the Strategist trigger.
8. Repeat from step 4.

This clever engine turns the simple act of dropping a land into a self-sustaining loop by leveraging Kodama of the East Tree's triggered ability whenever another permanent enters your control. As Dimir Aqueduct enters the battlefield, its bounce trigger returns it safely to your hand while triggering Thranduil the Strategist's landfall ability to forge a fresh Elf token. That new token's arrival feeds back into Kodama of the East Tree, allowing you to seamlessly drop Dimir Aqueduct right back onto the battlefield to repeat the cycle infinitely.
