Naturalized artifact destruction stapled to a body, sold at the rate red asks for it. The effect is mandatory, not a "you may," and that cuts both ways: the trigger demands a target, so casting it into a board where the only artifact on the table is one of yours forces you to blow up your own permanent. Read it as a removal spell with a 3/3 attached rather than a beater that happens to clean up an artifact, because the trigger fires on entry, not at instant speed. You commit it on your own turn, into whatever the board looks like, with no option to hold it up as interaction; an opponent with a sacrifice outlet or a way to flicker their own permanent in response gets to dodge the kill, and you are left having paid four mana for a body and a fizzled trigger. The upside over a dedicated destroy spell is durability: the spell that answers one artifact sits dead in hand when there is nothing to point at, while the creature keeps applying pressure once its job is done. It sits in a long line of "destroy an artifact, get a creature" packages that green and white have run repeatedly, the red cut that swaps lifegain or extra value for a slightly more aggressive frame, and it earns its keep only where artifacts are dense enough to guarantee a target you actually want gone.
