Best Save for Fomortiis?

The plan was originally to use him with Winter Alfred so is a physical savior and let Fomo handle magic.

I just realized that A/R Briar M Save doesn't exist, only S/R. While Atk+4 isn't changing much, I got to thinking and maybe a different save is better for him.

Fomortiis doesn't have immediate access to NCD so it makes his staff matchup less good, and offensive dragons aren't really a problem in the game currently. So he's mostly a defense against tomes, and his Special will be nullified by Freyja.

Is Physical better for him and best to wait for another magic tank? Or maybe standard Far Save?
