Scathbitch and Cu Cthucunt

Just get a decent saber, mash and any support and you're set.
I went arts team with Tamamo saberlot waver and things went well, I can add you if you want, I've got a 10/10/10 waver and a saberlot with a mlb CE

Use a maxed out Mordred with a high first and third skill and mlb ce. Her first skill is buster buff and her third skill can remove np seal and give np.

I was able to 3 turn this with Waver and double mlb ce Mordreds.

used modred 10/10/10 with CE princess of white rose, waver and mash. Also used brilliant summer master equip: deadly trident to pierce Cu evasion.

Go and borrow someone else saber.

Just solo Scat and Chu using OG Nero with white CE then clear it with just 15 turn, no need for difficult line up or etc.
