You can find it in this Yu-Gi-Oh! card set Invasion of Chaos
A deck-archetype that reigned over all tournaments prior to the creation of the Forbidden List, it is these monsters and "
Yata-
Garasu" that were blamed for the creation of the Forbidden List in the first place. The trademark Chaos cards are
Chaos Emperor Dragon - Envoy of the End (commonly abbreviated to CED),
Black Luster Soldier - Envoy of the Beginning, and
Chaos Sorcerer. When they were first released,
Chaos Emperor Dragon and
Black Luster Soldier were the two that were used, because
Chaos Sorcerer's effect didn't seem to make it worth playing at the time. The original Chaos Deck relied on discarding Light and Dark Attribute monsters and removing them from play to meet the popular Special Summoning conditions of the Chaos monsters. With their powerful effects, ability to be easily summoned, and high attack power, the Chaos monsters could easily dominate an opponent. It is of popular opinion among the best players in the game that Black Luster Soldier is the better card, for its ability to remove from play helpful monsters used by many during this time such as, Sangan, Witch of The Black Forest, Sinister Serpent, and others that had to be sent to the graveyard to get their effects.
