I see your point, Iskandaar and Medusa, with the right Masters have B. So I guess that's acceptable? 

Okay, so the three miracles could basically be anything then? They would be single use abilities that could be entirely situational? So, for instance, if Roland was in a dire fight with Saber, one of his miracles might duplicate his horns effect and give him a second wind? If that's the case I do like that concept better.
