Pro Tour Dragon's Maze

Pro Tour Dragon's Maze was the last Pro Tour of the 2012–13 season. The event had 388 competitors, and took place on 17–19 May 2013 in San Diego, California, United States. The formats were Block Constructed and Return to Ravnica block Booster draft, and was the first constructed premier event where Dragon's Maze was legal. The final day featured two players in their fourth Pro Tour top eight: Josh Utter-Leyton and Makihito Mihara, but it would be White Aggro specialist Craig Wescoe who earned his first Pro Tour trophy in his third Sunday appearance; he defeated Arizona native Dusty Ochoa in the final.

Day one
As with the previous Pro Tour, the event started with a Booster draft (Return to Ravnica block). The featured player was Luis Scott-Vargas, who drafted Red-Green-Blue to a 1–2 record. Players who got off to a better start included Bob Maher, Jr., Paulo Vitor Damo da Rosa, Darwin Kastle, reigning World Champion Yuuya Watanabe, and Tomoharu Saito, playing in his first Pro Tour since his suspension in 2010; these players all started 3–0. Return to Ravnica Block Constructed featured a variety of decks, but the most popular by far was Esper Control, with over 27% of players opting for the Sphinx's Revelation deck. Other decks included Bant Control, Selesnya Aggro, Junk Midrange, and a host of other midrange decks. One deck that garnered considerable attention was the Maze's End deck, predominantly piloted by Swedish players. At the end of the day, one perfect record remained; this belonged to level 2 judge Rob Castellon, who was playing a four-color midrange deck with Sire of Insanity and Deadbridge Chant.

Day two
Rob Castellon continued his undefeated run in the second draft, standing atop the field with an 11–0 record after winning pod 1. The featured player for the second draft was Hall of Famer Bob Maher, Jr., who was sitting on 6–1–1. His four-color deck did not yield much success; he ended up going 0–3 in the draft, and ultimately missed out on a money finish in the event. Famous players who did find success included Craig Wescoe, Gabriel Nassif, Patrick Chapin, and Player of the Year hopeful Josh Utter-Leyton. Nassif came close to his tenth Pro Tour top eight, but faced against Makihito Mihara in round 14, he made a mistake by not keeping mana up for Plasm Capture, and failed to advance; instead, it would be Mihara who would make it to his fourth Sunday appearance after defeating Brian Kibler in the next round. Josh Utter-Leyton would clinch the Player of the Year title by making the top eight of the tournament, and faced by a win-and-in situation against David Sharfman in round 15, he did not fail. Another player making a return to the Sunday stage was Matej Zatlkaj, who finished second at PT Berlin 2008, but had not played on the Pro Tour for a couple of years; he got the win in the penultimate round against Rob Castellon to make it in. Finally, three players couldn't make it to the final eight, but had significant matches in the last round nonetheless: Luis Scott-Vargas, Ari Lax, and Reid Duke. Scott-Vargas and Lax faced each other in a match for top 16 where the winner would hit Platinum in the Pro Players Club; meanwhile, Duke played Denniz Rachid in a match where he would qualify for the 2013 World Championship with a win, and fail to make Platinum with a loss. In the end, Scott-Vargas and Duke won their matches, finishing 11th and 9th, respectively.
