I just spent an entire 2 hours being karl with a friend's challenge team. I regret everything. I used 6* ulkina, matah, narza and a 5* elaina, all with lvl 9 bb and 1 sphere slot. I wish I could have the time back already >.< took an hour just to beat the regen. Adding in a decent damage dealer would make it workable, I guess.
