Provenance

Where it came from

Guardian Slime was introduced in the 2020 Yu-Gi-Oh! TCG booster set Legendary Duelists: Rage of Ra. This set was designed to provide modern support for the Egyptian God cards, specifically mirroring the deck strategy used by the character Marik Ishtar in the original anime series. The card was created to serve as a versatile utility monster, offering both defensive capability and the ability to search for iconic spell or trap cards associated with The Winged Dragon of Ra.

The artwork features a gelatinous, defensive construct that captures the aesthetic of Marik’s duel monster repertoire. As an Ultra Rare card within the set, it was received favorably by players for its synergy with high-level god card strategies. Its design emphasizes its role as a tactical component, intended to bridge the gap between early-game protection and the summoning of powerful endgame boss monsters.
