Number 86: Heroic Champion - Rhongomyniad

Number 86: Heroic Champion - Rhongomyniad first appeared in the Yu-Gi-Oh! TCG within the 2015 World Superstars booster set. The card was designed as part of the 'Heroic' archetype, which draws heavy aesthetic and thematic inspiration from Arthurian legend and mythic warriors. Its design intent centered on creating a high-risk, high-reward Xyz monster that gains increasingly formidable defensive and offensive capabilities based on the number of Xyz materials attached to it, ultimately serving as a centerpiece for specialized rank-four deck builds.

The card was illustrated by the Konami design team to embody the legendary spear Rhongomyniad, presented here as a towering, heavily armored knight. Within the competitive community, the card became notorious for its ability to completely lock down the opponent's board when fully empowered. Because of this overwhelming play pattern, it has faced significant regulatory scrutiny, eventually earning a place on the Forbidden list in various competitive formats to maintain the balance of the game.
