This is the corrupt version of Saber’s Excalibur: "Excalibur Morgan". While I still personally prefer the normal Excalibur a little more, I find this version to be really cool looking.

I really liked how destructive and amazing the Noble Phantasm “Excalibur Morgan,” was portrayed in the “Heaven's Feel" movies, and it was my inspiration for the visual at the end.

The other things I like about Salter’s NP are the unique details--like how she tosses her weapon from one hand to the other. Also, the fact that her attack is an upward slash, in contrast to her more regal, downward slash in the normal version.
