Springheart Nantuko + Overlord of the Hauntwoods + Spelunking + Dictate of Karametra

Springheart Nantuko

Overlord of the Hauntwoods

Spelunking

Dictate of Karametra

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. Dictate of Karametra 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 turns a simple combat phase into an exponential avalanche by leaning on land-type generation and token copying. When you declare Overlord of the Hauntwoods as an attacker, its ability creates a land token, which Spelunking ensures enters the battlefield untapped instead of slowed down. That sudden arrival triggers Springheart Nantuko's landfall ability, letting you pump mana—generously doubled by Dictate of Karametra—to copy the attacking Overlord. Each new token copy enters the battlefield to spawn yet another land, feeding right back into the Nantuko to snowball into an infinite army of copies and landfall triggers.
