So, while we're not using mechanics, there's no reason we can't scour errata for interesting builds, right? 
	
A further thought: What sort of power scaling should we aim for? I mean, we all know the potential of an unrestrained wizard. Also, how exotic are allowed to get? Like, I'm just assuming that Pun-Pun level shenanigans won't be permitted, but would playing, like, outsiders be acceptable?
