Springheart Nantuko + Mutable Explorer + Amulet of Vigor + Lotus Cobra

Springheart Nantuko

Mutable Explorer

Amulet of Vigor

Lotus Cobra

How it works

1. Play a land.
2. When the land enters, Springheart Nantuko triggers, causing you to pay 1 to create a token copy of Mutable Explorer.
3. When the Mutable Explorer token enters, it triggers, creating a Mutavault land token that enters tapped.
4. When the Mutavault token enters, Springheart Nantuko, Amulet of Vigor and Lotus Cobra trigger.
5. Resolve the Amulet of Vigor trigger, untapping the Mutavault token.
6. Holding priority, activate the Mutavault token by tapping it, adding C.
7. Resolve the Lotus Cobra trigger, adding .
8. Resolve the Springheart Nantuko trigger, causing you to pay 1 to create a token copy of Mutable Explorer.
9. Repeat from step 3.

This loop transforms a single land drop into an engine of exponential growth by turning your mana production into token multiplication. As you drop lands, Lotus Cobra provides the initial energy while Springheart Nantuko leverages its landfall ability to continually clone Mutable Explorer. Because every Mutable Explorer token brings along a Mutavault token, Amulet of Vigor is vital for instantly untapping those entering lands so you can tap them right back for colorless mana to keep the cycle going.
