"XX-Saber", pronounced "Double X-Saber" (ＸＸ（ダブルエックス）－セイバー, Daburuekkusu-Seibā) is a series of cards that is part of the "Saber" and "X-Saber" archetypes. To date, all "XX-Sabers" wear red capes and have electricity or what appears to be an electric aura in their card art. These monsters are still "X-Saber" monsters, with the second "X" simply indicating the expansion of the "X-Saber" team from ten to twenty members.
