2) Truenamer, 3.5, Tome of Magic. Well, it has better flavor, at least. But how about a class that uses skill checks to cast spells (ahem, utterances), except those spells just don't function very often? And if you do actually succeed in casting a spell utterance, your reward is that all your utterances for the rest of the day are even harder to cast? Just for fun, since the class uses the 3.5 skill system, which isn't really balanced around controlling skill progression, you can eventually load up on magic items to be so good at skill checks that you can gate in solars many, many times a day?
