Springheart Nantuko + Mutable Explorer + Lotus Cobra + Kaya, Geist Hunter

Springheart Nantuko

Mutable Explorer

Lotus Cobra

Kaya, Geist Hunter

How it works

1. Activate Kaya's second loyalty ability by removing two loyalty counters from it, causing you to double any tokens you create this turn.
2. Play a land.
3. When the land enters, Springheart Nantuko triggers, causing you to pay 1 to create two token copies of Mutable Explorer.
4. When the Mutable Explorer tokens enter, they trigger.
5. Resolve the first Mutable Explorer trigger, creating two Mutavault land tokens that enters tapped.
6. When the Mutavault tokens enter, Springheart Nantuko and Lotus Cobra each trigger twice.
7. Resolve the Lotus Cobra triggers, adding 1.
8. Resolve the Springheart Nantuko trigger, causing you to pay 1 to create two token copies of Mutable Explorer.
9. Repeat from step 4.

This loop relies on Kaya, Geist Hunter’s negative ability to double your token production, turning a single land drop into an expanding cascade of creatures and mana. As you play a land, Springheart Nantuko uses its landfall ability to copy the changeling Mutable Explorer, which in turn drops tapped Mutavault tokens straight onto the battlefield. Those new land entries trigger Lotus Cobra to continuously refund the mana needed to keep the cycle going while feeding right back into Springheart Nantuko's copying engine.
