Have you tried Typhon? She's pretty good here.
I even mentally AFK two times and let Warf die once and didn't drop all pillars on Mandy so Mandy killed Amiya by pillar drop before Amiya killed her, still cleared it.
Yu S1 is fantastic here, even more when you park Liskarm behind him and make her feed SP to Spot/Gummy so you can use their skill non-stop (yes, the fireballs explosions activate Liskarm's talent).
Just deploy all ranged operators first (texas and fang are fine for DP) then deploy the defenders and you can take it easy until like 350 where a big wave of shooters can kill Typhon, and you need to rotate Ptilo's skill and Spot/Gummy's skil.
