Savage Punch

Green's fight effects have always carried a structural risk: you point your creature at theirs, and if the math goes wrong you trade your good creature for their worse one and a card. The two-mana rate here pays for itself only if the math favors you, and the ferocious clause is the lever that bends it. With a power-4-or-greater creature already in play, the fighter swells before damage is dealt, which lets a midsized attacker punch up into something it could never survive trading with on its own profile, and the creature granting the bonus often is not the one doing the fighting. That conditional pump is the whole design tension: cast it before a fatty has landed and you are stuck handing a fragile attacker a duel it has to win on raw stats; cast it once the threshold is met and the +2/+2 swings the exchange decisively, letting your creature eat a far larger blocker and walk away (fight is still a mutual exchange, so it has to survive the return damage, but a buffed body usually does). It is fight tuned for the decks that want it most, the ones already committed to large bodies, rather than a generic answer any green deck can lean on. The reward scales with how deep you are in the strategy that makes fight risky in the first place, a tidy way to keep a cheap removal-adjacent effect from being correct in every green deck that wants to point a creature at a blocker.
