Sooo... can we make a master that fights on par with servants? I remember that teacher in fate ubw who was boosted by caster and almost killed saber 1v1. Or even kid Emiya could 1v1 servants.

God, no. Obviously I'm not the GM, but barring some very, very special circumstances Masters just aren't anywhere near the same level as a Servant. Servants are powerful enough that outside of specialized circumstances like Grail Wars, a Master shouldn't even be able to summon one. 

Master vs Master combat is one thing, but a Master vs a Servant is just going to get wrecked if they actually try to fight.
