CMLL announced that they would be holding a second En Busca de un Ídolo ("In search of an Idol") tournament in 2013, indicating that this could potentially become a recurring annual tournament for CMLL. The tournament will start on May 17, 2013 and run until Julyu 21, 2013 with all matches taking place in CMLL's main building, Arena México. CMLL announced the eight participants for the tournament at the same time. Most of the 2013 En Busca de un Ídolo have been active wrestlers longer than most of the 2012 contestants, shifting the focus from "youth" to where wrestlers generally work on CMLL shows. None of the 2012 participants were included in the announced field for the 2013 tournament. The "Theme" of the 2013 show was "Ahora o Nunca!" ("Now or Never"). The first round of the tournament will involve a Round-robin tournament format where each member of the tecnico (wrestlers who portray the good guys) team will face all four members of the rudo (bad guy) team between May 21 and June 11. The top two point earners from each group will then face off in the second round between June 21 and July 5. The finals of the tournament is slated for July 12, 2013.
Wrestlers could earn points in a couple of ways during the tournament.
20 Points for a victory
10 Points for a draw
0 points for a loss
The tournament also include four judges, referee El Tirantes, Tony Salazar, Último Guerrero and Brazo de Plata. The judges can award up to 10 points each based on a wrestlers performance, including the way they portray their character, their personality, their charisma, and how much of a fan response they get during their matches.
