Prime Slime was a five-card Secret Lair drop dedicated to Slimes and Oozes, reimagining several recognizable creatures and spells with a unified, playful aesthetic. Illustrated by Wizard of Barge, the borderless alternate-art cards showcased his distinctive colorful style while exploring different interpretations of Magic's gelatinous creatures. The drop combined a highly cohesive creature theme with several established cards, giving it appeal to both Slime enthusiasts and collectors drawn to unusual Secret Lair art treatments.
The total value includes bonus cards only if all are guaranteed to be included.
