The club spent three seasons there until a division championship, won without dropping a game, earned it promotion to Germany's highest league.

A championship there earned the side promotion to the Regionalliga Ost, where it spent another two years before making a return to the 2nd Bundesliga.

It was to be a short visit, the Rebels came last and were forced to play the Düsseldorf Panther in the promotion-relegation round.

The Rebels came second in the northern division, behind the Hamburg Blue Devils but were spared the promotion round when the last placed GFL team, the Assindia Cardinals, decided to withdraw from the league to the GFL2 for financial reasons.

Again the Rebels finished fourth and lost their quarter final in Schwäbisch Hall, but this time the Unicorns needed an overtime.

Only a half win short to division champs New Yorker Lions and runners-up Dresden Monarchs they finished third.
