What if the Saracens had that Monk refund as a baseline bonus instead of a UT? What would you replace Madrasah with?

I think it's safe to say that most Saracen players don't rush out a Castle for this tech, and many probably skip over it entirely. But with the Burgundians getting a gold refund on Knights whenever they die, it made me think that Saracens could get Madrasah as a baseline rather than having to research it. Then perhaps they could get a new CA UT.

It just feels like a Monk refund should be baseline, IMO. Such a bonus isn't that strong as a UT, or at least not worth getting a Castle.
