Sacrificing Ghost Council of Orzhova to its own ability means it will wind up in the graveyard, not exiled.

Normally, Ghost Council of Orzhova will return to the battlefield at the end of the same turn it's exiled. But if it's exiled during the End step, it's too late to return it this turn. It has to wait to return to the battlefield until the next End step.

When Ghost Council of Orzhova is exiled, any Auras or Equipment on it fall off and any counters on it are removed. When it returns to the battlefield, it comes back untapped and is treated as a new version of the card.
