Yeah! There once were:
Der Steinkönig (Stoneking) 2011
Der mysteriöse Phönix (Phöenix) 2011
Angriff auf Bramamir (Attack on Bramamir) 2011
Stelle Artaban wieder her! (Rebuild Artaban) 2011
Das Grab des König Hrimnir (The grave of king Hrimnir) 2012
Der verlorene Tempel (The lost temple) 2012
Would be great to rebuild the option to get those collecters cards from these modes, too.
Also the dark tower needs more floors and wie are still missing missions for pirates and stone-linkers.
