Chaos Betrayer

Chaos Betrayer was first introduced to the Yu-Gi-Oh! Trading Card Game in the 2020 Tin of Lost Memories Mega Pack. This set functioned as a compilation, gathering some of the most prominent cards released during the previous year of play to provide players with more accessible versions of high-demand cards. The inclusion of this effect monster reflected the ongoing evolution of light and dark attribute strategies that have defined the game's competitive landscape for many years.

The card’s design centers on the recurring themes of dual-attribute synergy, allowing players to banish light or dark monsters from the graveyard to special summon itself. Visually and mechanically, it fits into the broader Chaos archetype, a group of cards celebrated for their versatility and reliance on graveyard manipulation. While it occupies a common rarity, its design intent was to provide utility to players building decks focused on banishing effects and grave-based resource management.
