Mycosynth Lattice + Krark-Clan Ironworks + Spirit Loop

Mycosynth Lattice

Krark-Clan Ironworks

Spirit Loop

How it works

1. Activate Krark-Clan Ironworks by sacrificing Spirit Loop, adding 2.
2. Spirit Loop's second ability triggers, returning itself to your hand from your graveyard.
3. Cast Spirit Loop by paying 2, attaching it to a creature you control.
4. Repeat.

This loop relies on Mycosynth Lattice to fundamentally alter the battlefield, turning every permanent—including Auras like Spirit Loop—into an artifact. With that global transformation in place, Krark-Clan Ironworks can accept Spirit Loop as a sacrifice to generate generic mana. When Spirit Loop hits the graveyard, its native triggered ability immediately returns it to your hand, allowing you to recast it and repeat the cycle for an infinite storm count.
