He competed in qualifying block B on March 5, 2013, for a place in the finals; the other wrestlers in Block B included Genesis, Robin, Sensei, Super Halcón Jr., Disturbio, Guerrero Negro Jr., Inquisidor, Taurus, and Zayco who competed in a torneo cibernetico, multi-man elimination match.

[7] In late March, 2013 Oro Jr. was announced as one of the Novatos, or rookies, in the 2013 Torneo Gran Alternativa, or "Great Alternative tournament".

[9][10] On March 24, 2014 Oro Jr. was one of 16 men competing for a spot in the 2014 En Busca de un Ídolo ("In Search of an Idol") tournament.

The following week Metálico turned Rudo for the first time in his career as he attacked Oro Jr. at the end of a match against Canelo Casas, Disturbio and El Rebelde.
