Springheart Nantuko + Mutable Explorer + Lotus Cobra + Mondrak, Glory Dominus

Springheart Nantuko

Mutable Explorer

Lotus Cobra

Mondrak, Glory Dominus

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 elegant loop transforms a single land drop into an engine of exponential growth by exploiting the interplay between landfall, token doubling, and changelings. As you kick things off, Mondrak, Glory Dominus quietly supercharges the entire operation by doubling every token created, turning single copies into pairs. This allows Springheart Nantuko to churn out twin copies of Mutable Explorer, which conveniently triggers Lotus Cobra to immediately recoup the mana needed to keep the loop going. Meanwhile, every Mutable Explorer brings in a Mutavault token due to its changeling nature, feeding right back into the landfall triggers to repeat the process indefinitely.
