Glaze Fiend

A 0/1 flier that dares you to make it lethal in a single combat step: every artifact entering on your turn stacks another +2/+2, so a board that flickers or churns through a handful of cheap artifacts can turn this into a four- or six-power evasive threat for one swing. The pump is the whole engine, and it lives entirely in the word "enters," which is the design tension worth noticing. The bonus is fleeting (it lasts until end of turn), so the creature is something you assemble in a single window rather than grow across a game, ideally on the turn you intend to attack. That places it squarely in artifact-density shells where casting two or three trinkets in a turn is routine, and it punishes the opposite plan: hold the artifacts back and you have a 0/1 with flying doing nothing. The illusion typing and the zero power are honest about what it is. This is a payoff that asks the deck around it to do the heavy lifting, and the reward scales linearly with how many artifact triggers you can cram into one main phase. Token-makers, cheap equipment, and artifacts that bounce to hand all feed it, but the card never pretends to be more than the sum of what enters alongside it.
