Springheart Nantuko + Overlord of the Hauntwoods + Amulet of Vigor + Heartbeat of Spring

Springheart Nantuko

Overlord of the Hauntwoods

Amulet of Vigor

Heartbeat of Spring

How it works

1. Declare Overlord of the Hauntwoods as an attacker.
2. Overlord of the Hauntwoods triggers, creating a tapped Everywhere land token.
3. When the Everywhere token enters the battlefield, Amulet of Vigor and Springheart Nantuko trigger.
4. Resolve the Amulet of Vigor trigger, untapping Everywhere.
5. Holding priority, activate Everywhere by tapping it, adding .
6. Heartbeat of Spring triggers, adding .
7. Resolve the Springheart Nantuko trigger, causing you to pay 1 to create a token copy of Overlord of the Hauntwoods.
8. When the Overlord of the Hauntwoods token enters the battlefield, it triggers, creating a tapped Everywhere land token.
9. Repeat from step 3.

This loop turns a single attack into an unstoppable cascade of multiplying threats by leveraging a clever intersection of landfall and mana-doubling. When Overlord of the Hauntwoods attacks, it drops a Everywhere token that enters tapped, instantly waking up thanks to Amulet of Vigor while also satisfying Springheart Nantuko's landfall condition. Tapping that newly untaped Everywhere generates mana that is instantly doubled by Heartbeat of Spring, providing the exact funds needed to pay for Springheart Nantuko's copy ability. This spits out a fresh copy of Overlord of the Hauntwoods, which immediately enters the battlefield to trigger the whole sequence all over again, generating boundless land tokens and creature copies.
