Springheart Nantuko + Mutable Explorer + Anointed Procession + Lotus Cobra

Springheart Nantuko

Mutable Explorer

Anointed Procession

Lotus Cobra

How it works

1. Play a land.
2. When the land enters, Springheart Nantuko triggers, causing you to pay 1 to create two token copies of Mutable Explorer.
3. When the Mutable Explorer tokens enter, they trigger.
4. Resolve the first Mutable Explorer trigger, creating two Mutavault land tokens that enters tapped.
5. When the Mutavault tokens enter, Springheart Nantuko and Lotus Cobra each trigger twice.
6. Resolve the Lotus Cobra triggers, adding 1.
7. Resolve the Springheart Nantuko trigger, causing you to pay 1 to create two token copies of Mutable Explorer.
8. Repeat from step 3.

This clever loop turns a simple land drop into an engine of endless multiplication, anchored by Anointed Procession doubling every single token generated along the way. When a land enters the battlefield, Lotus Cobra provides the mana needed to fuel Springheart Nantuko's landfall ability, which copies the changeling Mutable Explorer. Because Mutable Explorer enters the battlefield and immediately replaces itself with a Mutavault land token, its own entry triggers a cascade of fresh landfalls that feed right back into Lotus Cobra and Springheart Nantuko to keep the exponential growth going forever.
