Where it came from
Karumonix, the Rat King was introduced in the 2023 Magic: The Gathering set Phyrexia: All Will Be One. As a legendary creature, it was designed to support the long-standing tribal synergy of Rat decks, offering a unique lord effect that grants toxic and card advantage to the player’s battlefield. The card emerged during the storyline where the Phyrexians attempted to complete the multiverse, reflecting the grotesque, biomechanical aesthetic of the New Phyrexian landscape.
The artwork for this specific promotional version was crafted by the artist Wisnu Tan. In keeping with the aesthetic of the set, the illustration emphasizes the swarm-like, unsettling nature of the character, blending biological rat traits with the cold, metallic infusion characteristic of the Phyrexian influence. It was received by the player base as a significant boon for Commander players looking to bolster their tribal strategies, specifically those favoring a relentless, aggressive playstyle centered on the Rat creature type.
