Springheart Nantuko + Overlord of the Hauntwoods + Mana Flare + Archelos, Lagoon Mystic

Springheart Nantuko

Overlord of the Hauntwoods

Mana Flare

Archelos, Lagoon Mystic

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 Archelos.
3. When the Everywhere token enters the battlefield, Springheart Nantuko triggers.
4. Holding priority, activate Everywhere by tapping it, adding .
5. Mana Flare 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 dazzling loop relies on Archelos, Lagoon Mystic keeping your permanents entering the battlefield untapped, allowing every new Everywhere land token created by Overlord of the Hauntwoods to arrive ready to tap immediately. By tapping that fresh land and doubling its output with Mana Flare, you easily generate the exact mana needed to pay for the landfall ability of Springheart Nantuko attached to Overlord of the Hauntwoods. Each iteration yields a fresh token copy of Overlord of the Hauntwoods, which in turn triggers to produce another Everywhere land token to perpetuate the cascade.
