Double-Edged Sword Technique

Double-Edged Sword Technique was introduced to the Yu-Gi-Oh! Trading Card Game as part of the Ra Yellow Mega Pack, released in 2012. This set was designed to collect various cards previously featured in the Yu-Gi-Oh! GX animated series and associated media, providing players with easier access to cards centered around Jaden Yuki's classmates and the themed decks of the Obelisk Blue and Ra Yellow dorms. The card itself functions as a support piece for the Six Samurai archetype, allowing players to special summon two of these monsters from the graveyard at the cost of taking battle damage equal to their total attack points.

The design of the card reflects the high-risk, high-reward playstyle of the Six Samurai, focusing on rapid field presence at the expense of player life points. As a trap card, it requires strategic timing to maximize the utility of the monsters returned to the field. Its inclusion as an ultra-rare in the Ra Yellow Mega Pack made it a sought-after aesthetic and tactical choice for collectors and competitive duelists alike who favored the aggressive, synergistic nature of the Six Samurai deck strategy during that era of the game.
