Forcing the pace of junior hockey player development the team was quite successful in the following years. Placed 1st after the 1961–62 season the EVL lost the promotion ties against TSC Eintracht Dortmund, but the consecutive season they beat Dortmund and promoted to the ice hockey Bundesliga. Without acquiring new players the Landshut-based team started in their first Bundesliga season 1963-64 as underdog and candidate for relegation. The home games attracted up to 10,000 people. Surprisingly the team reached the fifth place out of eight. 1965 marked the beginnings of a friendly relationship with HC Sparta Praha, e.g. regarding training camps and friendly games. In 1967, ten years after the construction of the ice rink, the stadium was roofed and converted into an arena. That year the EV Landshut signed coach Karel Gut from Sparta Praha for three years. In his first year at the Isar his team was placed third. The following year was rather disappointing: Being placed fourth, the squad had to play relegation. The 1969–70 season preliminary round, being under pressure to perform, was finished on the first place. As the champions round was also dominated by Landshut, the team won the German championship for the first time. The hockey euphoria in the city was immense, four out of ten home games were sold out. The most decisive players of the season were Alois Schloder, Rudi Hejtmanek and goalie Sepp Schramm. In the 1970-71 European Cup Landshut defeated SG Cortina but was disqualified due to an unlicensed player.
