Hm... how far does allowing "Everything" go? Is homebrew in that set, to a point? Because
there's a particular class I've always wanted to try.
Burlew's done work in some 3.5 splatbooks in the past, so I trust his homebrew is of sufficient quality.
edit: oooh, and he's since added improved features and some feats to let the class keep pace with other classes/be able to multiclass more easily.
