Best duo with a... mag?

[bubur]

Got a partner who is dead set on being a mag of evil variety.

We're not gonna be big league pvp'ers any time soon, maybe ever.. but we wanna hold our own against any equal level non-twinks.

Whats a good leveling class duo with mag?

another mag?
sham?
cler?

If I can be a melee I'd prefer that I guess but anything would be fun
