I think your best bet is taking Sol + Hades and building a beast Dark Team around it, furthermore that we should get a Dark Raid event for a weapon soon, maybe miracle for Amon Unleashed or Satan and running Mordred with EX Ambush until you get an A Frame Defense Debuffer, sadly you missed on Lu Bu Ren (B Frame Atk and Defense debuffer) but you can work it out, your account doesn't seem as bad as the only I re-roll for when I was a newbie but still, those Himes aren't any good, Thor is decent but Thunder is ass overall until Mammon...

Good luck on any choice you make.
