Signal Pest

A 0/1 that does nothing in a vacuum, which is exactly the point: this is a payoff dressed as a creature, an anthem you cast on turn one and attack with every turn after. Battle cry is the engine, pumping every other attacker by one power, and the design pairs it with an evasion clause that solves the obvious problem of a zero-power body sitting uselessly in front of a blocker. Because it can only be stopped by flying or reach, it keeps swinging into clogged ground boards, and every swing reprices the whole team. The trade the designers made is visible in the stat line: no power of its own, so it never threatens lethal alone, and a single point of toughness, so it dies to almost anything that bothers to look at it. What it offers instead is a colorless, one-mana anthem that goes in any aggressive shell regardless of tribe or color, the kind of artifact-creature glue that fast decks rarely got before. The closest reference points are the standalone anthems (Glorious Anthem and its kin), but those cost more, sit on the back foot, and ask nothing of the board. Signal Pest inverts that: cheap, attached to an attacker, and scaling with the width of your assault rather than a fixed buff. The wider the swing, the louder the signal.
