Run Over

The fight family buys its efficiency with symmetry: your creature deals damage, but it takes damage back, so the trade rewards toughness as much as raw power. This one drops that clause entirely. Your creature deals damage equal to its power to an opponent's creature and takes nothing in return, which is the older Prey Upon design inverted into one-sided removal. The cost is paid elsewhere, in the reduction: point it at a Mount or Vehicle you control and it falls to a single green. That is the whole reason the effect stays fair, because it is fight-style removal built specifically for go-wide aggression on oversized bodies, where a saddled attacker or crewed machine is already carrying far more power than its base rate suggests. Instant speed opens the window a one-sided fight wants most: fire it during combat after blocks, or in response to a removal spell, to wring one last hit of damage out of a creature that is dying anyway. The constraint is the one every fight variant shares, since you need a creature already on the board; it does nothing from an empty hand into an empty side. But with the board in place, it functions like burn priced in green, no red required, tuned to reward the exact aggressive shell it was made to support.
