Sébastien "Ceb" Debs, originally using the handle 7ckngMad, first appeared in Dota 2 shortly after the game’s launch in 2011 with Team Shakira, an all-French roster. The squad established itself as one of Europe’s best squads at DreamHack WInter 2011 by taking fourth, a performance that saw the squad sponsored by Western Wolves. Ceb spent a few months with this team before joining Troels "Synderen" Nielsen’s mTw.
mTw scored an impressive victory at DreamHack Summer 2012 and enjoyed strong performances in a number of other events. The team cleared the western qualifiers for The International 2012 and entered the event as a serious contender. Despite this, the team floundered to a 3-11 finish in the group stage and was eliminated in short order. Ceb split off and reformed Team Shakira after the event.
This was followed by a strange time that included team name changes, a brief partnership with Meet Your Makers, and Ceb trying out a coaching role.
He returned to action as a player with his former Team Shakira teammates, who were now competing under the name of DD.Dota. DD.Dota suffered from frequent roster turnover but made it into the wild card qualifier for The International 2013, which resulted in the team being sponsored by Quantic Gaming. The team failed to move forward into the event after a dramatic loss to RattleSnake.
Quantic’s roster troubles worsened after TI3, which resulted in Ceb splitting away from Quantic and forming a new team under the DD.Dota name. A new roster was finalized and a sponsorship came through from Sigma. The roster posted mixed results throughout the year and Ceb was dropped after six months.
What followed was an extended journeyman run from Ceb with multiple stints with teams, some of which were as brief as just a few days. The most notable team Ceb competed with during this time was Denial Esports. None of these tenures included strong finishes in notable tournaments.
Ceb’s run as a journeyman ended with him joining Alliance in 2015. The team posted mixed results, with the highlight coming in the form of a second-place performance in the joinDOTA MLG Pro League Season 2. The team failed to qualify for The International 2015, which led to Ceb’s departure.
Following TI5, Ceb had unsuccessful tenures with Monkey Freedom Fighters and Kaipi. This seemingly marked the end of Ceb’s time as a player, as he transitioned into casting and then transitioned into coaching full-time with European team OG, which impressed with a victory in the Frankfurt Major. Ceb showed that his mind for the game remained sharp by helping OG win three more majors in the following years.
Despite dominating Valve-sponsored majors, OG disappointed in The International, falling well short of the top at both TI6 and TI7.
The introduction of the Dota Pro Circuit was followed by a disastrous fall-off for OG. The team struggled with roster issues throughout the 2017-2018 season, which saw Ceb return to action as a stand-in in a variety of roles.
When Gustav “s4” Magnusson and Tal “Fly” Aizik shockingly left OG to join Evil Geniuses, Ceb was penned in as the team’s replacement off laner. The roster was rebuilt ahead of the qualifiers to The International 2018 with the return of Anathan “ana” Pham and addition of Topias “Topson” Taavitsainen.
OG stunned the Dota 2 scene by winning The International 2018.
Ceb remained with OG after TI8, but the team struggled after ana took an indefinite leave from the roster. This resulted in the team struggling to lock down a suitable replacement at the carry position. ana eventually returned, but the team continued to underwhelm in the Dota Pro Circuit. Despite that, OG earned enough points in the Dota Pro Circuit to earn a direct invitation to The International 2019.
Ceb and the OG roster won the event, becoming the first players to be two-time TI champions.
The OG roster took an extended hiatus from pro Dota 2 after The International 2019, which ended with the announcement of a new roster built around Johan “N0tail” Sundstein and Topson. As part of this, Ceb announced his retirement from professional Dota 2 in order to transition into an administrative position with OG, which was expanding into other esports including Counter-Strike: Global Offensive.
In 2020, Ceb returned to action as a substitute in multiple positions. Ahead of the introduction of Valve-sponsored regional leagues, Ceb announced his official return to action as OG’s off laner.
