The antonyms for "more even-steven" can be "uneven," "lopsided," "disproportionate," "unfair," or "biased." While even-steven suggests a balance or equality, the opposite terms reflect an imbalance or lack of fairness. For instance, a team winning a match with a score of 10-0 can be considered uneven, while a judge's decision that favors one party over the other can be seen as biased. The word "more" in "more even-steven" implies a comparison between two or more situations, where one is relatively more balanced than the other. Therefore, using antonyms helps in communicating the specific nature of the situation and the extent of its imbalance.
