Here you are anon, I replaced a few operators because a few of the ones on your list are built on my account. Don't forget that enemies target the last deployed operator in their range, so if your ranged operators are getting nuked it's because you should bait attacks with a melee unit. Your AA sniper, May, (with Mountain) should also be able to handle them because their DEF is low. I don't recommend Yu if you're alright with replacing him-- his DEF is on the lower side so the final waves might fuck him up. Instead, Gummy or Cuora might be better. I used Beagle here, though.

>Yu -> Beagle
>Surfer -> Vanilla
>Mountain -> Flint
>May -> Kroos
>Amiya -> Steward
>Gitano -> Lava
>Podenco/Kazemaru/Almond got the boot and I brought Ansel and Hibiscus (healers) instead

I didn't use Specter's skill.

There will be inconsistencies considering how many alternatives I brought despite my attempt at using low rarity operators, so if you're worried you can always borrow a support operator. As >>531992404 said, Lin might be a good pick because of the final 50 enemy caster spam.
