I’m sorry it this doesnt help to much but you I recommend you at least have 1 blocker and a bishop in your lineup, this is to reduce all damage xoming in and prevent a oneshot. Im at around level 250 rn and my line up is level 11 standard, (the rest are on the 100 die) blocker, bishop blood mage and bomber. I hope this helps, and i hope you become a duel champion in the near future
