What about Caster's master in Unlimited Bladeworks. With Caster reinforcing his fists, he was able to lay a pretty solid beat down on Saber. Even if he did get the first shot due to surprise, I don't find it very hard to believe he could go head to head with Saber. My character is the same, but if you were to throw a Beserker at him, he probably wouldn't hold up very well, and some other abilities would definitely be a bit too much for him to take on. Plus, I don't expect him to beat any of the servant's he's facing, unless they re really weak, just fight them until Caster able to deal with them. Plus, since this Caster can create something like mechanical golems, he probably won't be fighting alone.

He only won cause he had the element of surprise and Saber underestimated him. Saber quickly got up and was about to finish him off. And remember he is being reinforce by Caster who uses magic that is beyond what even the strongest Mages can even hope to achieve. Not to mention Saber had a terrible master who was weakening her.
