Fyndhorn Bow

Three mana per use, capped at one creature a turn by the tap symbol, and the keyword evaporates at end of turn: this is renting first strike, never owning it, and it captures exactly how early-era design throttled combat abilities. Before Equipment existed, handing out a combat keyword repeatably meant an artifact that charged full freight on every activation, with nothing left on the board afterward. That pricing scheme aged faster than almost anything from its period. Later cards welded first strike directly onto bodies, baked it into permanents that stayed put, or handed it over at a tiny cost, leaving this design vocabulary stranded. The one genuine virtue is timing: the activation is instant-speed, so you can hold it past the declare-attackers step and ambush a blocker or steal a profitable trade after the board has committed. But that ambush costs three mana to manufacture a single point of combat advantage, and the arithmetic rarely beats spending those three mana on a removal spell or a creature outright. The game stopped charging this tax long ago, and the rate has not improved with age.
