The good thing about corrupted Ushiwakamaru is that she doesn't have the annoying buff&NP remover unlike the Bel Lahmus. However, she still has annoying skills, and her NP will kill almost all servants if it hits. There will be THREE of them because she creates clones of herself in the first two turns of the battle.

The key to taking down this battle is to kill the original Ushi, since she's the only one that creates the clones. The original Ushi has a servant trait on her so having Gil will be helpful. As for chaos tide, it's best to have servants that can heal the entire party, so having Jeanne or Merlin would cover that. I'd say the hardest part of the battle is keeping track of your HP throughout the battle since -1,200 HP per turn adds up quickly. If you keep that in mind, Arash is also a useful servant to put in battle because of his low cost and his suicide AoE NP (you don't really have to worry about losing HP since he's meant to die). Low cost is important since you can't have your best 3 in the front and use the other slots for bond exp (I don't think I'm not the only one...) due to the earthquake at the beginning of the battle.

Ushiwakamaru herself is quite a straightforward enemy, with an NP charge skill (although it is for all enemies) and a crit damage buff applied after her NP. Note that her NP is relatively weak, and Ruler servants can probably take a hit (only ~8500 damage) and survive. As for other classes, I'd doubt that they'd survive unless they have defensive buffs. Speaking of defensive buffs, Mashu is as always useful because of her 0 cost and her self target + invincibility skills for enemy NP.

Regarding CE, I think it's not really something to think about; just use whatever works best for each individual servants. But if I had to choose some, anything that has defensive buffs would fare better than offensive CE's, since the battlefield has chaos tide. NP charge CE's are also pretty useful since your servants probably only have enough HP to fire their NP once (or twice if you're lucky/have a survival team) Mystic codes should be your preference.
