The 2006 Leyenda de Plata started on August 25, 2006 with the first of two eight-man cibernetico qualifying matches. The cibernetico saw Black Warrior eliminate Rey Bucanero as the last man in a match that also included Heavy Metal, Metro II, La Máscara, Último Guerrero, Mephisto and Misterioso, Jr.. With Black Warrior winning the first cibernetico it was not too surprising that Místico won the second cibernetico as the two had been involved with a long running storyline feud throughout 2006. Místico outlasted Mr. Águila, Negro Casas, El Sagrado, Volador, Jr., Averno and Alex Koslov. The semi-final on September 8, 2006 saw Místico defeate Black Warrior, followed by a "mask vs. mask", Luchas de Apuesta challenge from Black Warrior that Místico accepted for the CMLL 73rd Anniversary Show. On September 15, 2006 Místico defeated Atlantis to win the Leyeda de Plata, overcoming interference from Atlantis' corner-man Black Warrior. After the match Black Warrior stole the Leyenda de Plata trophy and ran off with it, furthering their feud.
