IcyCool said:But, given your line of reasoning. A wizard (given sufficient caster level) should be able to say that he wishes to call "One of the Dark Eight" (thus specifying a kind of creature), and not only would one of them have to come, but the wizard would have full control over it.
... Which is why you should use *my* line of reasoning.

The phrase "Deities and unique beings" represents a particular kind of creature - examples include the Dark Eight, the Righteous Captain of the Most Heavenly Host, Lolth, etc.
An advanced creature, though possibly powerful, is not a "deity or unique creature" until he crosses the subjective line described above.
If all solars are stock MM solars, except for the Righteous Captain of the Most Heavenly Host (who is the only solar advanced to 34 HD) then it's not possible to use Gate to get a 34 HD solar.
