Technically the restriction on Magical Resistance is correct as a rank A will be virtually imune to modern magic and rank B blocks anything below a three-line incantation. But I guess I can reduce Phantasmagoria's power.

And the rule that Masters can't defeat Servants was proven wrong several times through F/SN.

I did some research on the wiki and Shirou has 27 circuits, but their quality is so bad that the quantity is almost meaningless. And Rin has 40 and an extra of 30, I think. But the wiki doesn't explain much on the quality other than saying this character is good, that one isn't. But I guess that'll cut for now.
