Fight Removal

The 'Fight,' 'Bite,' and 'Punch' answers to creatures, predominantly green. Fight spells/abilities make two creatures deal damage to each other (Prey Upon, Pounce, Epic Confrontation, Pit Fight) or do so repeatably (Ulvenwald Tracker, Arena). 'Bite' effects deal damage equal to one creature's power to a target creature without taking damage back (Rabid Bite, Bite Down, Hunt the Weak). This fills a real gap: removal.spot_removal is destroy/exile only and removal.burn is instants/sorceries dealing damage to any target or a player, so neither catches creature-vs-creature combat removal. Distinct from sacrifice.fling and other 'throw your creature's power at a face' burn, which aim at any target rather than answering a creature.
