Lore

Why it matters

Karumonix, the Rat King represents a significant piece of Phyrexian lore, serving as a legendary creature that rewards players for building a specialized tribal deck around Rat synergy. Its striking artwork by Jason A. Engle captures the unsettling, biomechanical aesthetic central to the Phyrexia: All Will Be One set, making it a sought-after card for those who collect thematic or creature-focused decks.
