Been trying to get a good answer but i get to complicated answers. is 7k enough with MG with out HB? do Shadowers have to worry that much about touch dammage? Don't need hp washing tips btw
The highest magic damage is around 9800 so you are safe with meso guard if you stay out of direct contact, but you will have to spam it when there's mass dispel.
You'd be living on edge with the bishop spamming magic guard too. There's a chance you could be dispelled and seduced at the same time and that might result in you eating rocks with just your HP.
