Assassin is alright. Move him to the CS tab whenever you can.

[@King Cosmos]
Likewise.

While the idea is good. We have a few issues here.

I could allow Proof of Friendship to stay if you already didn't have a composite skill as the 1st of your skills despite my request to avoid those when they aren't absolutely needed.

Even taking Proof of Friendship out, I feel unsure about accepting that composite skill because it's two really strong effects combined into one. Natural Body alone would make more sense with the angle you are going with, in my opinion.

Also, no using Rho Aias as an offensive attack. That goes completely against the intent of the Noble Phantasm.
