The Casas/Panther Hair vs Hair match in March 2012 is mandatory viewing imo. It's unlike a traditional Hair vs Hair match which usually revolves around a bloody brawl, but I found their human chess like match to be acceptable deviation from the norm and in-keeping with the body of their feud. Similarly, El Hijo Del Santo & Villano IV vs El Hijo Del Solitario & Angel Blanco Jr from TXT 2/25/12 is a sensational bloody brawl, complete with a typically engrossing Santo performance. Virus/Guerrero Maya also have a 2011 title match which is incredible, my apologies if that was the one you've seen because they had one in 2013 as well. I haven't seen the 2013 one, but have heard good reports.
Panther/Casas also have a lightning match (ten minute time limit) on 1/27/12 which is also a superb teaser for their lengthier hair vs hair bout. I recall the matwork being very good with Panther busting out a mixture of rugged and violent holds, with Casas more than enhancing the match quality with his brawling and expressive selling.
I also thought Fuego/Valiente vs. Arkángel de la Muerte/Virus from CMLL 2/21/12 was an outstanding tag reminiscent of past Lucha glory. However there were a few divided on the match who saw other problems, but those who loved the match gave it extremely high praise.
Aside from that, there is an abundance of 80s and 90s Lucha of outstanding quality. I'll quickly link the absolute essential viewing:
Sangre Chicana vs MS-1, Hair vs Hair (9/23/83)
http://www.youtube.com/watch?v=A0WXVFXtDSc (ignore the date on video, it is the '83 match)
The definitive Lucha bloody brawl imo. Chicana's selling is incredible, the build and payoff to Chicana's initial comeback is exemplary and true lucha perfection, and the crowd are frenetic and add to the piercing tension in the final caida.
El Satanico vs Gran Cochisse, (9/14/84)
Perhaps a top three Lucha title match I can recall seeing. Very little of Satanico is widely avaiable sadly, but what we see here arguably demonstrates his superlative ability.

Sangre Chicana vs Perro Aguayo, Hair vs hair (2/28/86)
Maybe eclipses the famous '83 Chicana/MS-1 match. There's very little between them imo, and once again Chicana's mere presence and charisma within this bloody environment is as enthralling as peak Jerry Lawler.

El Hijo Del Santo vs ***** Casas, (7/18/87)
I'm of the opinion that Dandy/Casas is better than the best Santo/Casas match, probably Santo/Espanto as well. However this is a true gem in their series and demonstrates why their chemistry is revered by Lucha fans.

El Hijo Del Santo vs Espanto Jr, (4/10/88)
I sadly don't have a link to their mesmerising 8/31/86 match, but this is a fine subsitute.

Satanico vs Sangre Chicana, (5/26/89)
Two of the very best in a superb outing.

El Satanico/El Dandy/Emilio Charles Jr. vs. Atlantis/Javier Cruz/Angel Azteca, (5/13/90)
Regarded as one of the best trios matches, it's a perfect lead into Dandy/Azteca for the title a few weeks later.

El Dandy vs Angel Azteca (6/1/90)
Fabulous title match, very highly regarded in close Lucha circles.

El Hijo Del Santo vs Brazo De Oro, Mask vs Hair, (1/13/91)
Santo in apuestas matches is a thing of beauty and Brazo is more than a fine hand himself. A simple equation that delivers a satisfying result.

Blue Panther vs Atlantis, (8/9/91)
The definitive Lucha title match. The matwork is so graceful and engrossing, but the beauty is in the timing and attention to detail in each hold. This isn't an exhibition, with a real sense of struggle for every hold and it truly feels as close to a legit sporting contest between two consumate professionals as you could get in Lucha.

Los Infernales vs Los Brazos, (11/22/91)
Just sheer greatness.

Trio Fantasia vs Thundercats, Mask vs Mask (12/8/91)
http://www.youtube.com/watch?v=oNwsIirQpew
Timeless chaotic bloody brawl which truly captures the spectacle of an apuestas match. Amazing punches, violent bumps and just sheer insanity throughout the twenty minutes.
El Dandy vs ***** Casas, (7/5/92)
One of the absolute best matches Lucha has produced. Simply extraordinary.
http://www.youtube.com/watch?v=o8IJh6AaF-Y
Felino vs Ciclon Ramirez, Mask vs Mask (7/9/93)
Classic.

El Dandy vs Javier Llanes, (3/11/94)
Exemplary grappling contest and a true gem of El Dandy's career, which is saying something. Very few Lucha matches will feature better grappling than you'll see on display in this one.

Ciclon Ramirez vs Javier Cruz, Hair vs Hair (6/10/94)
Legendary bout.

Blue Panther vs Atlantis, (12/5/97)
Not on par with their '91 classic, but that's no slight on another great installment in their series.
