Fluxo Part Ways With Coach tacitus After Roster Changes and Early 2026 Struggles

Brazilian CS2 organization Fluxo have officially ended their partnership with head coach Marcos “tacitus” Castilho, bringing an end to his 21-month tenure at the helm of one of South America’s most high-profile Counter-Strike rosters. The decision comes amid a difficult start to 2026 for the team, which has struggled to find consistent results on both regional and international stages. 

Departure of tacitus

Marcos “tacitus” Castilho, 26, leaves Fluxo after joining the organization in April 2024, just before the addition of veteran in-game leader Andrei “arT” Piovezan. Together, tacitus and Fluxo navigated through one of the most turbulent competitive periods in the club’s modern history, including numerous roster adjustments and high expectations that were only partially realized. 

In his own announcement on X (formerly Twitter), tacitus described 2026 as a “transition period” for the team, citing structural changes and leadership adjustments within the roster as major challenges. He acknowledged that early results were below expectations, which ultimately “forced the organization to make changes in order to look for better results quickly.” 

Fluxo’s Competitive Record under tacitus

During tacitus’s period as coach, Fluxo managed to qualify for two Valve Majors:

• BLAST.tv Austin Major (2025) – Finished 15–16th

• StarLadder Budapest Major (2025) – Finished 9–11th

While reaching Majors was a significant milestone for the Brazilian side, Fluxo were unable to progress beyond Stage 1 in either tournament. Despite flashes of strong play — including a 2–0 start at the Budapest Major before being eliminated — the team frequently stumbled in best-of-three series. Prior to this, tacitus had commented on the pressure of maintaining momentum after an impressive start in such events. 

Regionally, Fluxo secured numerous domestic titles in South America, taking home trophies at events like the Desafio Brasileiro de Esports Finals and Circuit X Retake São Paulo, as well as various CCT (CCT Global / CCT Lock-in) competitions. However, these domestic successes did not consistently translate into deep runs against international opposition. 

Recent Struggles and Ranking Drop

Fluxo’s form has taken a clear downturn in the early weeks of 2026. After early exits in the IEM Rio Americas Closed Qualifier and disappointing results at multiple domestic LANs, the squad slipped in the Valve Regional Rankings (VRS) — falling from 38th to 63rd globally. The results pressure contributed to the organization deciding to overhaul leadership and coaching. 

Broader Roster Changes

The coaching departure is the second significant change within Fluxo in recent weeks:

• In January 2026, Fluxo benched long-time in-game leader arT, ending his roughly 19-month run as captain for the team.

• Shortly after, they signed Raphael “exit” Lacerda, formerly of MIBR, to fill arT’s roster spot. Lucaozy was confirmed as the new in-game leader instead of exit.

These moves reflect Fluxo’s attempt to inject new tactical leadership and experience into their lineup after a mixed 2025 and shaky start to the new year.

Fluxo’s Current Lineup

As of February 2026, the Fluxo active roster consists of:

• Romeu “zevy” Rocco

• Kayke “kye” Bertolucci

• Lucas “Lucaozy” Neves – team leader

• Lucas “decenty” Bacelar

• Raphael “exit” Lacerda (recent signing)

Additionally:

• Matheus “mlhzin” Marçola is currently benched.

At least for the moment, Fluxo have not publicly announced a replacement coach following tacitus’s departure.

Context: Fluxo’s Competitive Journey

Fluxo first began gaining international attention in 2023 and 2024 after assembling a Brazilian core that combined experienced players with young talent. Early expectations were that this lineup could contend in South America and steadily break into the top 30–40 globally. During the initial phase of tacitus’s tenure and arT’s leadership, Fluxo routinely competed in regional leagues and secured qualification for major international events — albeit without the deep runs fans had hoped for. 

Fluxo’s broader trajectory also mirrors a trend seen with other Brazilian organizations, where domestic dominance does not always transition to consistent success against North American and European sides. Several Brazilian squads — including Legacy (formerly with arT after he left Fluxo) — have undergone significant roster churn in recent months due to missed competitive benchmarks. 

Outlook

At the time of writing, Fluxo have not revealed who will take over coaching duties after tacitus’s exit. With a revamped leadership lineup and a renewed sense of urgency, the organization will be hoping to stabilize results and climb back up the VRS rankings.
