Casting mass removal—cards that clear multiple creatures or permanents simultaneously, like Wrath of God, Damnation, or Toxic Deluge—requires careful timing to maximize value. There might be various scenarios but you should be able to analyze each clearly.

In Magic: the Gathering, timing your spot removal—single-target removal spells like Swords to Plowshares, Fatal Push, or Abrupt Decay—is crucial to maximize its impact and avoid wasting valuable resources. This is particularly true if you are not that familiar with the deck build.
