Mvemba a Nzinga, the leader of the Kongo civ, has the following ability:
Religious Convert
May not build Holy Site Districts, gain Great Prophets, or found Religions. Gains all Beliefs of any Religion that has established itself in a majority of his cities. Recieves an Apostle each time he finishes a M'banza or Theater Square (of that city's majority Religion).
Does that mean it is impossible for this civ to win using religious victory?
