This ingenious loop relies on Mycosynth Lattice to turn everything—including Mintstrosity and Nim Deathmantle—into artifacts, transforming your creatures into fuel for Krark-Clan Ironworks. When you sacrifice Mintstrosity to the Ironworks, it triggers its own death ability to create a Food token while simultaneously triggering Nim Deathmantle. You can then sacrifice that newly created Food token to the Ironworks for even more mana, effortlessly funding the {4} cost required by Nim Deathmantle to return Mintstrosity straight back to the battlefield. Because Mintstrosity keeps replacing itself with a sacrificeable artifact while feeding the very artifact that revives it, you generate an endless cascade of enters-the-battlefield, leaves-the-battlefield, and death triggers.
