Several ways to go, I would recommend:
A: Magic, with spellcasting and counterspelling as the two skills - forget summoning with the hit to Magic you will take.
B: Resources, mainly to get two good cyberarms plus cybereyes, for 2 to 3 points of Magic loss.
C: Attributes - take an Intuition tradition, make Agility, Strength, and Charisma dump stats (the former two because you will be using cyberarms for that).
D: Skills - one ranged and one melee skill, a low assensing skill, a few other basic runner skills such as perception.
E: Metatype - human, 3 Edge still isn't bad.
Not practical at all if it was a combat mage, but functional as a healing/utility mage where high spell force and lots of successes are not quite as important. Be sure you are actually okay with a concept character - ask yourself if you will care whether other characters outperform you, or not.
