So I wanted to make a legitimate mage character this time around in Oblivion.
I was planning on making a mage with primary skills of Illusion, Destruction, Mysticism, and alteration
For this build, which birth sign is better and why? And which Race is better and why?
To maximize your magicka you could go with Altmer with Atronach. I, however, kind of find it annoying not to have magicka regen with a pure magical character. You must rely on potions and stone to recover.
Altmer + Apprentice = suicide against magic users, since Altmer are already have a weakness to magic.
Altmer and mage is the "safe bet". You don't get as much magicka, but you get only the Altmer's "weakness to magic"
Breton is more fun I think, as they can be more diverse, but start out with less magicka. Breton with Mage birthsign is the absolute safest bet. Breton with Apprentice is pretty fun and doesn't make you feel "too powerful".
