Gust-Skimmer

A 2/1 for two generic mana that any deck can run, with an evasion toggle gated behind a color it may not even play. That split is the whole proposition: the creature deploys in any shell, but the flying only matters where blue mana flows, so the artifact half pays the cost of entry and the activated half rewards the deck that happens to be the right color. The repeatability is the quiet part. Because the ability can be used every turn, the flying isn't a one-time evasion grant but a per-turn option that converts spare blue mana into reach over the air, useful for slipping past a clogged ground stall or pressing damage when the board has locked up. Colorless creatures that ask a specific color to unlock their best line are a recurring artifact-design pattern: the body is universal currency, the upside is a tax on commitment to one color. Here the tax is gentle and the payoff is modest, two power in the air for a single blue, which keeps the card honest as a low-rarity aggressive piece rather than a build-around.
