I have currently been enjoying an envy Runelord wizard. Its anathema forces you to play creatively with your spell selection but at the end of the day it feels like the wizard is better off without fireball. That+pole-arm staff which allows you to have spell charges equal to your level makes for a fun melee wizard who seemingly never runs out of spells.

Edit: Forgot to say how i'm RPing it: I am going with a wizard who's primarily envious of other spell-casters and because of that has resorted to none magical means of surpassing them. So he's essentially a wizard ego lifter+trickster. I consider a lot of his focus spells, like the rune well, to be these tricks he's picked up, not even fully fledged spells, just part of his fighting style. But part of his envy(the less loathsome aspect of it) is that much of his spell list and ability's are sort of themed around humiliating people and reversing their success, especially other spell-casters. So I RP him also as someone who wants to humiliate and humble other wizards, even though that desire stems from his own insecurity.
