Aztec Warfare
Aztec Rumble is a Lucha Underground match type, invented by Dario Cueto. Luchadors entered at timed intervals, similar to a royal rumble, and are eliminated by pinfall or submission. There is no disqualification, countout, or over the top elimination.
(These are similar to the rules used some years by IWRG's Rey del Ring.)
Aztec Warfare I
The first Aztec Warfare was taped on October 5, 2014 at the Lucha Underground Temple. It aired on El Rey on January 7, 2015 and on Unimas on January 10, 2015. It was a 20 luchador match where the winner would become the first Lucha Underground Champion. The interval between entries appeared to be 80 seconds.
The first and last entrances were determined by results on the previous episode. Mil Muertes defeated Fenix, giving Muertes the last entry and Fenix the first. The other 18 participants were not officially announced prior to show, and order of entry was also not revealed until each man was waved in. Teaser videos indicated Drago and Super Fly's place, and implied where others must have come in.

Aztec Warfare II
The second Aztec Warfare was taped on December 12, 2015 at the Lucha Underground Temple. It aired on El Rey on March 23, 2016. It was a announced as a 20 luchador match.
The announcers alluded to a plan of it originally being to determine a #1 contender, and being changed to a Lucha Underground Championship match moments after Fenix defeated Mil Muertes for the championship. Catrina also decided Fenix would start the match and Mil would be twentieth and last person in the match. Catrina also refused to allow Pentagon Jr. in the tournament. (Her enemies Angelico, Son of Havoc and Ivelisse were also noticeable absent.) Mil was shockingly eliminated quickly after a Pentagon Jr. attack. Dario Cueto returned moments later, introducing his brother Matanza as a special 21st entrant. Matanza defeated all the remaining luchadors to win the match and the championship.
The interval between entries was announced as 90 seconds, but usually were quicker.

Aztec Warfare III
The second Aztec Warfare was taped on April 9, 2016 at the Lucha Underground Temple. It aired on El Rey on November 16, 2016, as the 11th episode of the season. 20 luchadors participated.
Dario Cueto announced the return of Aztec Warfare four episodes before it took place, and placed his brother and then champion Matanza as #1 to prove his dominance. Drago won the 20th spot by defeating his trios champion partners Fenix & Aerostar, which also eliminated those two from participating. Jeremiah Crane, Ivelisse, Marty Martinez, Mariposa and the Mack won another qualifier match, eliminating Killshot, Dante Fox, Cage, Texano Jr. and Argenis from participating. However, Ivelisse was broke her foot during the match and was unable to participate. Ricky Mandell, in his first match under that identity since season 1, was implied to be her replacement.
Johnny Mundo originally drew the 12th spot, but was switched to the 2nd spot after annoying Dario Cueto prior to the match. Sexy Star had drawn 2, and was moved to the 12th spot.
Rey Mysterio pinning Matazna was the first time Matanza had been defeated on the show; Matanza injured Mysterio after the match. Angelico returned after being injured after Ultima Lucha 2, attacking Worldwide Underground. Black Lotus also returned with the Black Lotus Triad to similarly attack Pentagon Dark for breaking her arm at Ultima Lucha 2.
Sexy Star defeated Mil Muertes to become the fifth Lucha Underground champion and first female champion.
The interval between entrances was not specified, and varied (likely due to editing.)
