Wild Instincts

Green's fight spells live or die on the buff attached to the fight, and the +2/+2 here is the whole proposition. A naked fight is a coin-flip trade that asks your creature to survive the swing it deals; bolting the pump onto the same card tilts the math, so a creature that would die in an even exchange now comes out ahead and a removal-as-fight effect becomes reliable rather than situational. The trade-off is the rate: at four mana, sorcery-speed, this is paying a premium for the safety the buff provides, where leaner fight cards gamble on already having the bigger body. It is the deliberately overcosted, deliberately consistent end of the fight spectrum, the version you run when you want the removal to actually kill the thing rather than hoping your creature was big enough on its own. Worth noting that the buff resolves as part of the same spell, so it applies before damage is dealt: there is no window for an opponent to respond between the +2/+2 and the fight, which is what separates a built-in pump like this from casting a combat trick and a fight spell as two separate cards an opponent can interact with in between.
