Up until 2010 the tournament format was that of eight tag teams facing off in a one night, single elimination tournament, sometimes with a match to determine the seeds for the tournament. In 2010 the field of competitors was doubled to 16 and the tournament would take place over three shows, with eight teams facing off in Block A, the other eight in Block B and the two block winners would wrestle the following week. All tournament matches except the finals are single fall matches, while the finals are a best two-out-of-three falls per "lucha libre" traditions.
