Provenance

Where it came from

Koma, World-Eater was originally introduced in the 2021 Magic: The Gathering expansion Kaldheim, drawing inspiration from Norse mythology and the world-spanning serpent Jörmungandr. This specific version is a special reprint featured in the Foundations Promos set, collector number 121s, which serves to make iconic creatures more accessible to players while celebrating the game's evolving visual history.

The artwork for this piece was crafted by Mark Zug, a veteran illustrator known for his dramatic and textured depictions of fantasy monstrosities. Zug designed the creature to emphasize its overwhelming, multi-part nature, utilizing a color palette that evokes the cold, cosmic dread of the deep cosmos. Upon its release, the card was lauded by the competitive community for its complex mechanical design, which focuses on generating and sacrificing tokens to control the battlefield.
