Springheart Nantuko + Mutable Explorer + Nissa, Resurgent Animist + Horizon Explorer

Springheart Nantuko

Mutable Explorer

Nissa, Resurgent Animist

Horizon Explorer

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 untapped due to Horizon Explorer.
4. When the Mutavault token enters, Springheart Nantuko and Nissa trigger.
5. Holding priority, activate the Mutavault token by tapping it, adding C.
6. Resolve the Nissa trigger, adding .
7. Resolve the Springheart Nantuko trigger, causing you to pay 1 to create a token copy of Mutable Explorer.
8. Repeat from step 3.

This intricate loop centers around Springheart Nantuko enchanted onto Mutable Explorer, turning every land drop into an engine for unending duplication. As each token copy of Mutable Explorer enters the battlefield, it triggers to generate a Mutavault token, which enters untapped thanks to Horizon Explorer's static ability ensuring your mana keeps flowing. Meanwhile, Nissa, Resurgent Animist tracks these continuous land drops to effortlessly fuel the loop's mana costs while digging through your deck.
