Hmmm. Perhaps I've missed something, but you CAN'T search ten provinces in ten consecutive turns with the same pretender.

It should be noted that Arcane Probing and Dark Knowledge only require a single point in the relevant magic paths, making them particularly good candidates for remote searches. Even a Lizard Shaman can find you all astral sites this way without items or empowerment, and a Revenant does the same for death.
