Four mana for unconditional destruction is the rate that gets ignored in a fast format and quietly drafted in a medium one, which is what TMT is. The card sits in the P1P5 to P1P7 band for any committed black drafter, and slides up to P1P3 once you are in WB Equipment or a BG Food shell, where the artifact-and-Food typing earns past the kill trigger.
The double-black is the real gate, and it gates harder than a Constructed instinct suggests. BB on turn four asks for eleven black sources, which a two-color black deck builds toward and a Mardu goodstuff pile rarely reaches. This is not a card you splash and then shuffle in and out between games; the mana base does not bend that way mid-match. It is a maindeck card for decks built around black or it is in the binder.
Against the format's bomb density, the unconditional kill is what black wants over Stomped by the Foot when the target carries evasion or a static ability: the legendary Turtles and Shredder, Unrelenting do not get easier to answer for being large. The pizza also clears a creature wearing Bespoke Bō, where size-conditional removal whiffs on a buffed body.
The coda is the tiebreaker once the artifact has resolved. The sacrifice ability has no timing restriction, so after the pizza is on the battlefield you can bank three life at instant speed in response to a race-deciding attack: it matters in the BG Food mirror where the clock tightens, and it triggers WB Lifegain payoffs without a dedicated slot. It is not why you draft the pizza. It is why the pizza beats a vanilla four-mana destroy.
