Hawkeater Moth

The name promises a predator; the card delivers a 1/2 flier whose only job is to be hard to remove. There is no activated ability, no trigger, no combat upside worth four mana: just flying and shroud, stapled together. What that combination buys is a flier the opponent cannot answer with point removal, so it sits in the air as a persistent blocker against small evasive threats and a perpetual nuisance against decks leaning on a single key flier. Green is the color of anti-air in Magic's pie, but it almost always pays that toll at sorcery speed or as a one-shot: reach on the ground, an instant that shoots one flier out of the sky, a sweeper that clears everything. A standing green body in the air is the rarer offer, and shroud is what makes the rate honest. Shroud protects the creature in both directions, so it can never be the target of your own pumps or auras either; it is purely a self-contained body that refuses to be dislodged by a one-mana removal spell. The 1/2 frame keeps it from doing anything an aggressive deck would want: it dies to almost any attacker it blocks, so it polices the smallest flyers rather than the format's real threats. Narrow engineering for the green deck that has lost the sky and wants a piece of it back without trading its turn for the opponent's removal spell.
