Mozilla used to be talented Guild Wars 1 player before joining League of Legends community. At the beginning he liked all roles, but after the Irelia release, he decided to focus on toplane. His skills gained from playing GW1 and other games allowed him to become one of best players in Czech Republic quite quickly. After passing through some of top Czech teams he decided to make his own team called REPLIKA (aka eXtatus lately), what should be the top team in Czech Republic. While forming this team he took players from some talented Czech teams like Kacenky or Buzici v Muzici what caused their disbandment.
However, after not winning some Czech important tournaments Mozilla felt into the dream of joining LCS and decided to leave eXtatus (what also caused its disbandment lately). Since that Mozilla was kinda unlucky in his eSport career. He joined Team LoL Pro, but they disbanded after unsuccesfull qualification on LCS. Then He got into Fnatic.Beta, but got benched for lacking individual skill, after that Fnatic.Beta disbanded.
- Known for his highly educational livestreams.
