The phrase "crystal-ball divined" implies a sort of mystical, fortune-telling certainty that something will happen. Antonyms to this phrase could include "ambiguous," "unclear," or "unknown." These words suggest a lack of certainty or a range of possibilities, rather than a definitively predicted outcome. "Improbable" or "unlikely" could also be used as antonyms, indicating that the likelihood of a certain event occurring is low or nearly impossible. Ultimately, the opposite of the phrase "crystal-ball divined" is any word or phrase that indicates uncertainty or the possibility of multiple outcomes, rather than a single, predetermined path.
