Pounce

Fight has always been green's compromise on removal: the color that can't burn a creature or exile it gets to point two animals at each other and let combat math sort the rest. What separates this version from the baseline fight spell is the instant speed. Where many of green's early fight cards locked the effect to sorcery timing (you swing your creature into theirs on your own turn, no surprises), this one moves the window to the end of an attack, after blockers, or on an opponent's combat. That timing flips the spell from a clunky pseudo-removal into a genuine combat trick: hold up two mana, let an attacker commit, and turn a creature you control into a removal spell that also profits from its own untapped body. The cost is the same constraint every fight card carries: you need a creature on the board big enough to win the exchange, and your creature takes the return damage, so a trade that looks clean on paper can leave your blocker dead or chumped into uselessness. That dependence on board state is why fight has never been priced as a clean removal spell. The instant-speed access is the lever that pushes this one past the rate it appears to offer.
