Each artifact this Beast destroys costs it a turn of its own life: the fade counters that mark its three-turn lifespan double as the ammunition for the destruction ability. Pay a mana and spend a counter to crack an artifact, and you have accelerated the creature's own expiration; let it sit and the counters tick away anyway on each upkeep, so the only question is whether the descent buys you anything on the way down. Green has long owned repeatable artifact hate, but most of its answers either trigger once on arrival or trade the body outright. This one meters the effect against a finite clock, charging each activation in a counter (and a token amount of mana) rather than in a recurring tax you can keep paying. The 4/6 frame is what keeps the trade from being a formality: a body big enough to demand a combat answer means the opponent rarely gets to stall and wait for the timer to run out on its own. Among the fading creatures of the era, most spent their counters passively, just counting down toward the sacrifice. This one turns the countdown into a resource, converting the drawback that defines the mechanic into a self-rationing supply of removal. The elegance is that the upkeep tax and the activation both draw from the same currency, so the card is always weighing its own remaining life against the next artifact it wants gone.
