Strength of the Coalition⁣ - Dominaria United⁣ (Uncommon)⁣ [180]

Strength of the Coalition is an instant spell that gives one of your creatures a temporary boost of +2/+2 until the end of the turn when you cast it for just a green mana. If you choose to pay an additional cost of {2}{W}—known as "kicking" the spell—you not only get the boost for your target creature but also place a +1/+1 counter on each of your creatures, making this a powerful option for swarming strategies. You'd want to play this card when you're looking to either push through damage in combat or strengthen your board presence, especially in a deck that can generate a lot of creatures. However, the downside is that if you can't afford the kicker cost, the effect is limited to just one creature, which may not be enough in a more competitive game.
