Provenance

Where it came from

Expanding Ooze was released in 2024 as part of the Modern Horizons 3 expansion for Magic: The Gathering. This set was designed specifically for the Modern format, incorporating a blend of reprints and new designs intended to introduce powerful mechanical synergies to existing card pools. As a common-rarity creature, it serves as a utility piece within the set's Limited environment, reflecting the design team's focus on creature-based growth mechanics.

The card was illustrated by long-time Magic contributor Randy Gallegos. His design focuses on the visual manifestation of the creature's growth ability, utilizing a characteristic color palette and texture associated with amorphous, slime-like entities in fantasy gaming. The artwork aims to convey the card's mechanical function of accumulating counters, fitting seamlessly into the aesthetic expectations for green-aligned biological threats within the game's broader lore.
