Q. In the other Type-Moon works, who else besides Arc can fight against Servants?
A. If we're working on the condition of one on one, with an extremely average Noble Phantasm. Generally most of the 27 Ancestors, Kishima Kouma, Aozaki Aoko.
If it's just a defensive fight, but would still be a fight, then Ciel. Shiki (Rakkyo), Shiki (Tsukihime) are no match for Servants....but Ryougi Shiki (3rd personality) might be able to go as far as the Ciel class.
Q. I have a question about the Servants vs. other character answer in the 9th issue of Comptiq. About a Servant with an average Noble Phantasm, who would have one and what rank would that have been?
A: That's a serious question. The level of the Noble Phantasm would be B, and ability being represented by numbers would be called an average Noble Phantasm. Broken Phantasm, Barrier of the Wind King (C), Gae Bolg (thrown) (B), that sort.
On the other hand, those with conceptual effects, destiny interference types fall into a special category. With Gae Bolg (regular), no matter how much Arcueid might be superior to Lancer in numbers, she will be killed depending on her luck, you see.
