You still have space get rid of one of fillers and put a better guy in there
Move scorp up front and surround him with poison gas / eaters/ touch users
Looks like you may have some bloodfury type skill monsters, try playing around healing/protecting those and having them 1 shot enemies with combinations of one-on-one, unwanted friend or sleep bombs.
Thats also the part where i got stuck im starting over
Yeah I can’t even beat the second guy in champion league or Thale and have forfeited the league 5+ times. I got screwed over on the spins and only have one super epic and one legendary darkrider (who dies way too easily even with healers) and like 6-7 epics. Tried to do the online missions to get more gems but I’m also stuck on the chapter 3 holy level 
Guys, what happens when I lose a league battle`?
