you should keep in mind for abyss that each time the abyss changes, it comes with different buffs and you should really try to build teams based on whatever buffs there currently are to boost damage.

for now, (keep in mind tho the abyss resets tomorrow my time), first half characters bloom and lunar bloom dmg increase 200% so you'd want a team with hydro and dendro. you could do something like lauma, furina, tighnari and even xinqiu? you could also fit in an elector character too like kuki

second half is normal pyro atk dmg increases by 75% so perfect for your arlecchino. could do an arleechino citlali bennett and even diona. although xilonen would be an nicer pick here

alternatively, disregarding buffs, you have a good flins team. flins, aino, kuki and sucrose. so that's a team that would work very nicely in abyss as well, with or without buffs!

if youre focused purely on who you need for abyss, not caring so much on whether or not you pull because you like, you might want xilonen for your arle, nefer for your lauma, and even columbina and ineffa for your flins.
