Nim Deathmantle + Krark-Clan Ironworks + Mintstrosity + Encroaching Mycosynth

Nim Deathmantle

Krark-Clan Ironworks

Mintstrosity

Encroaching Mycosynth

How it works

1. Activate Krark-Clan Ironworks by sacrificing Mintstrosity, adding CC.
2. When Mintstrosity dies, it and Nim Deathmantle triggers.
3. Resolve the Mintstrosity trigger, creating a Food artifact token.
4. Activate Krark-Clan Ironworks by sacrificing the Food, adding CC.
5. Resolve the Nim Deathmantle trigger from step 2, causing you to pay 4 to return Mintstrosity from your graveyard to the battlefield, and attach Nim Deathmantle to it.
6. Repeat.

This loop relies on Encroaching Mycosynth to fundamentally rewrite the battlefield, turning your creatures into artifacts so they can be readily fed to Krark-Clan Ironworks for mana. When Mintstrosity hits the graveyard, its own death trigger creates a Food token—which Krark-Clan Ironworks can *also* sacrifice for even more mana—while simultaneously fueling Nim Deathmantle's revival ability. By using the mana generated from sacrificing both the creature and its resulting Food, you easily pay the {4} required by Nim Deathmantle to bring Mintstrosity right back to the field equipped and ready to repeat the cycle indefinitely.
