Needlebug

An artifact creature whose entire purpose is being immune to artifacts, on a plane where artifacts are the texture of everything. That self-referential joke is the whole conceit: in an environment where removal, blockers, and threats were overwhelmingly metal, a body that could not be touched by any of it was quietly maddening to interact with. Protection from artifacts here means it dodges artifact-based removal, blocks artifact attackers with impunity, and slides under most of the answers such a metal-dense field offered. Flash is the part that turns it from a curiosity into a real beat: held up at instant speed, it ambushes an artifact attacker and walks away unscathed, or arrives at end of turn as a 2/2 that an artifact-heavy opponent simply cannot block or kill on their own terms. The rate is unremarkable in a vacuum, but the card was never built for a vacuum; it was built to be the wrench in a metal machine. Strip the artifact-saturated context away and the protection clause does almost nothing, and that fragility is by design: a creature tuned to one specific environment, sharp where that environment is dense and dull everywhere else.
