A warblade is a very nice choice. You got melee, casting (truespeaking), and skills. All int based.

You can self heal, use random spells (Factotum), and kill stuff. the Truespeaker functions much better when you are only useing it to cast quickened utterances to control the battlefield and self heal.

I would consider a 2 level monk dip still though. Int to ac when unarmored will prevent headaches with truespeaking being SLA's.
