I think all of the trial deck bosses have potential to be good because of the guaranteed persona ride. You can abuse the when persona ride is active cards. Only issue now is none of the clans have persona ride cards that are worth abusing
I like but hear me out. I run jewel core and corruptly peer as my main combo column . Core boosts peer for first attack core to soul, peer moves to back row open circle at end of battle. Then oseladgest swings call back out the core as 23k attacker (or anything that’s good at the moment) but core usually so it gets tucked again
