Warblade with Gestalt

[Satyr]

That's what Gestalt was originally designed for; to represent concepts like Mystic Theurge without need for multiclassing.

I would argue that the great merit of gestalt rules is that the additional layer of the character, more multi-dimensional and therefore round and interesting characters can be created to leave the stereotypical clichés of the class system behind .

It's a Duskblade. A really, really, really good Duskblade.

That would be one explanation, but it still doesn't work well with the Archivist - the perfect swordmaster of the Great Library is not really an enthralling concept (okay, actually it is. I give up).
