Mischievous tricks can be replaced with a variety of synonyms depending on the context and severity of the behavior. Some milder synonyms might include playful pranks, harmless mischief, or innocuous practical jokes. For more mischievous behavior, synonyms such as deceiving antics, mischievous shenanigans, or naughty capers may be used. In more severe cases, words like malicious schemes or deceptive plots may be more appropriate. It is important to consider the intent behind the behavior when selecting a synonym for mischievous tricks, as certain words may imply a more serious or harmful intent.
