Shatter on a body, with the destroy clause optional and stapled to a 4/3: the staple is the whole pitch. A dedicated artifact-destruction spell rots in hand when there is nothing to point it at, which is why so many of them live in sideboards rather than maindecks. Bolting the effect onto a creature solves that problem in a brute-force way. The destruction triggers on entry and is optional, so when the board is artifact-free you decline it and keep a serviceable beater; when an artifact does show up, you get the answer on top of the body you already wanted. The cost of that flexibility is efficiency: five mana for a 4/3 is a poor rate on its own, and the destruction is effectively sorcery-speed because it waits on the creature resolving, so it can never catch an equipment mid-combat or a mana rock the turn before it matters. This is the design pattern that lets a hate effect earn a maindeck slot without becoming a dead card: the artifact destruction is upside, the Beast is the floor. It is utility-hatebear thinking applied to red, a color whose usual answer to artifacts is to set them on fire; here the long-term value lives in the creature you keep rather than the spell you spend.
