Lightning Strike⁣ - Dominaria United⁣ (Common)⁣ [137]

Lightning Strike is an instant spell that allows you to deal 3 damage to any target, whether that's an opponent, a creature, or even planeswalkers. You'd typically want to play this card during your opponent's turn to remove a creature or to finish off a weakened opponent. Its main downside is that it costs two mana, which can limit your options if you have a lot of other spells to cast in the same turn, and it's less effective against creatures with high toughness.
