Provenance

Where it came from

Mask of Weakness was originally released in the early years of the Yu-Gi-Oh! Trading Card Game, serving as a tactical trap card designed to provide players with a defensive option during combat. It functions by allowing a player to target an opponent's monster and decrease its attack points by 700 during damage calculation, a classic mechanic intended to swing the outcome of an engagement in favor of the trap user.

The version found in the Speed Duel: Battle City Box, numbered SBCB-EN123, is a common-rarity reprint produced to support the faster, more streamlined Speed Duel format. The design reflects the game's iconic anime-inspired aesthetic, featuring stark, thematic artwork consistent with the series' long-standing visual language. While not a tournament staple, it remains a recognizable utility card for fans engaging with the Battle City themed set.
