Springheart Nantuko + Overlord of the Hauntwoods + Amulet of Vigor + Dictate of Karametra

Springheart Nantuko

Overlord of the Hauntwoods

Amulet of Vigor

Dictate of Karametra

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. Dictate of Karametra 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 an attack from Overlord of the Hauntwoods into an ever-snowballing swarm by leveraging the powerful synergy of several permanents. As the Overlord attacks, its trigger drops a tapped Everywhere token, which immediately wakes up thanks to Amulet of Vigor's passive untap effect. That freshly-untapped Everywhere is then tapped for mana, doubling its output via Dictate of Karametra's flash-enabled static mana-doubling. This provides the exact funds needed to pay for the landfall trigger of Springheart Nantuko (bestowed upon a creature), creating a brand-new token copy of Overlord of the Hauntwoods and restarting the entire cycle for infinite creatures and tokens.
