Springheart Nantuko + Primal Vigor + Destiny Spinner

Springheart Nantuko

Primal Vigor

Destiny Spinner

How it works

1. Animate a Forest that enters untapped using Destiny Spinner
2. Cast Springheart Nantuko for its bestow cost by paying 1, attaching it to the animated Forest.
3. Play a land. When the land enters, Springheart Nantuko triggers, causing you to pay 1 to create two token copies of the Forest that enters untapped.
4. When the Forest tokens enter, Springheart Nantuko triggers twice.
5. Holding priority, activate the Forest tokens by tapping them, adding .
6. Resolve the first Springheart Nantuko trigger, choosing not to pay and creating two 1/1 Insect creature tokens.
7. Resolve the second Springheart Nantuko trigger, causing you to pay 1 to create two token copies of the Forest that enters untapped.
8. Repeat from step 4.

This loop turns a simple land drop into an engine of endless growth, protected on the way by Destiny Spinner ensuring your setup spells slip past counterspells safely. By using Destiny Spinner's ability to turn a land into a creature, you create a valid host for Springheart Nantuko's bestow cost, setting up the entire recursion. From there, Primal Vigor supercharges the sequence by doubling every token generated, providing more than enough mana from the newly arriving lands to sustain the loop indefinitely.
