Springheart Nantuko + Overlord of the Hauntwoods + Spelunking + Mirari's Wake

Springheart Nantuko

Overlord of the Hauntwoods

Spelunking

Mirari's Wake

How it works

1. Declare Overlord of the Hauntwoods as an attacker.
2. Overlord of the Hauntwoods triggers, creating an untapped Everywhere land token due to Spelunking.
3. When the Everywhere token enters the battlefield, Springheart Nantuko triggers.
4. Holding priority, activate Everywhere by tapping it, adding .
5. Mirari's Wake triggers, adding .
6. Resolve the Springheart Nantuko trigger, causing you to pay 1 to create a token copy of Overlord of the Hauntwoods.
7. When the Overlord of the Hauntwoods token enters the battlefield, it triggers, creating a tapped Everywhere land token.
8. Repeat from step 3.

This loop transforms a simple attack from Overlord of the Hauntwoods into an overwhelming chain of reinforcements by leveraging land tokens to fuel an exponential creature-copying engine. When the Overlord attacks, it drops an Everywhere token onto the battlefield, which Spelunking ensures enters completely untapped and ready for action. Springheart Nantuko uses that landfall trigger to demand a small mana payment in exchange for a fresh copy of the attacking Overlord, an expense easily covered by tapping the new land and doubling its yield with Mirari's Wake. Every iteration spawns another Overlord token that triggers its own land drop to keep the cycle spinning, cascading into an infinite army of creatures and land tokens.
