Reckless Reveler

Artifact removal that walks onto the battlefield first is the whole trick here. Most colors answer an artifact with a dedicated spell that does nothing if there is no artifact to hit; this packs a Shatter-style effect onto a body, so the worst case is a 2/1 that still attacked while you waited. The Satyr is a maindeck-able beater until an artifact you care about resolves, at which point a single red mana and the sacrifice convert it into removal. That conversion is the design's balancing act: the artifact destruction costs you the creature, so you cannot keep the clock running and hold an answer open at the same time; you pick one. Note what the sacrifice clause does not do, though: it is bolted to the destruction effect, not a free outlet. There is no value to be wrung from sacrificing this against an empty board, because the ability requires a target artifact to activate at all. With nothing to destroy, the creature simply stays a creature. As color-pie work it is red doing what red has always done to artifacts, just stapled to a two-mana attacker so the slot is rarely wasted: if the opponent never deploys an artifact, you still get a body to send at their life total.
