I had three people with Holy.

Friggin' man, it was so much fun

I lost the first time because I forgot to keep one person zombified and she used mega death. (something like tidus with auto-med used a holy water on himself, he used one on auron in his next turn, and I was stupid and switched the third person out for a person that didn't still have zombie-_-) I was smarter the next time

It's not too hard to get the celestial weapons. Especially Yuna and Auron's. and I think Kimarhi's, but I"m sure there are mobs of people that would like to stab me with a butterfly net for saying that.
