Unlimited Blade Works - Honkai: Star Rail

Blade/Sparkle/Bronya/Fu Xuan team aka Unlimited Blade Works

Why did I pick Fu Xuan over Huo Huo for this team?
Several reasons:
- To avoid getting CC/Slow on Sparkle which will mess up the entire rotation.
- To activate Rutilant Arena on Blade (which doesn't matter here since he already has enough Crit Rate with 4 pc Longevous Disciple)
- To keep A Secret Vow active.
- To break Svarog's Grabby Hand with her Ult

...Is this Muramasa NP looping with Double Castoria?
