Springheart Nantuko + Mutable Explorer + Adrix and Nev, Twincasters + Lotus Cobra

Springheart Nantuko

Mutable Explorer

Adrix and Nev, Twincasters

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 brilliant loop starts when you drop a land to trigger Springheart Nantuko, using mana generated by Lotus Cobra to pay for its landfall ability and copy your Mutable Explorer. Because Adrix and Nev, Twincasters is doubling every token you make, each iteration floods the battlefield with multiple copies of Mutable Explorer alongside fresh Mutavault land tokens. Those entering Mutavaults immediately feed more landfall triggers back into Lotus Cobra to sustain the mana loop and spring more copies from Springheart Nantuko. The result is an explosive cascade of infinite creature tokens, lands, and mana, all built on the incredible synergy of these four pieces.
