Tooth of Chiss-Goria

Flash is the clause that drags this out of the pump-equipment also-rans and into combat itself. In an artifact-dense board the affinity discount can collapse the cost toward zero, and because it carries flash and enters untapped, it can be cast mid-combat and tapped the instant it resolves: a blocker steps in, the attacker gets +1/+0, the math flips. That window is the entire pitch. The design tension sits between a permanent that idles on the board (this is an Artifact, not an Equipment or a creature, so it just sits there until you tap it) and the recurring edge the tap ability hands you once it lands. The +1/+0 lasts only until end of turn, so any single pump is one combat's worth of help. What keeps it from being a disposable trick is that the artifact stays: the same tap is available across every future combat step, turning a momentary swing into a slow, grinding tax on every board stall. Each turn the same artifact can nudge one creature past a blocker or into a winning trade. The affinity tuning is doing exactly its intended job, rewarding decks built around a wide artifact battlefield rather than any deck that wants a generic combat trick. It rewards a board state rather than a single moment.
