Mirror of Oaths

Mirror of Oaths was released in the 2009 Yu-Gi-Oh! Trading Card Game set Raging Battle. It functions as a trap card designed to punish opponents who utilize cards that special summon monsters from their deck, forcing them to draw cards while the player who activated the trap special summons a monster from their own deck. This mechanic reflects the meta-game landscape of the late 2000s, where deck-thinning and rapid special summoning were becoming increasingly dominant strategies in competitive play.

The card's design features an illustration depicting a reflective, mystical surface, aligning with the dark and arcane aesthetic prevalent in the Raging Battle set. Like many common-rarity cards from this era, it was intended to serve as a niche technical counter or side-deck option. While it did not shift the core competitive scene, it remains a notable example of the era's focus on disruption-based trap design and the ongoing cat-and-mouse game between card acceleration and reactive control effects.
