Well, he's mostly alright except for a couple things:

- He has one too many Personal Skills. Also, his Magic Resistance is rather high for a Rider, being at the level of a high-end Saber. Even the story about he resisting a curse as a child shouldn't be enough to justify a B Rank for a Rider. His Riding should be at least A Rank as well. There are very few (and mostly weird) exceptions for the rule that mentions that Riders need an A Rank in Riding to qualify for the class. I'm willing to let you keep the 4 Personal Skills if you lower the MR to C and bump the Riding to A. Other wise, you'll have to rearrange your skills.

- I'm a bit disinclined to allow a Noble Phantasm that can passively give anyone control over the whole staging grounds of the Holy Grail War. You might need to either make some changes or ditch his first NP.

Other than those points, he's ok.

Your Servant is pretty much ok. Other than the fact that I'm not sure if I understand what her 3rd skill is meant to do, she is fine. If you could explain that it would be helpful.

Your Servant is fine as well. I don't see anything particularly worthy of mention regarding her but I think that her Noble Phantasm could be reworded to be a bit stronger. As it stands right now, it's little more than a bounded field that could be created with her own magecraft instead of being a NP-like effect.
