Heavy Mattock

The conditional bonus is the whole design: a flat +1/+1 for any creature, doubling to an effective +2/+2 the moment a Human carries it. That tribal kicker rewards a board built around one creature type, lifting a mediocre Equipment to a respectable one without inflating its rate for everyone else. The math is tuned around the equip cost: at to attach, the generic profile is overpriced, but the Human-only bonus shifts the value calculation enough to justify the slot when the right creatures are out. The card asks a question before it pays out, and answers generously only when the answer is yes. The result lives or dies by deckbuilding intent rather than raw stats, which is exactly the role low-rarity tribal payoffs are meant to fill: a quiet incentive to stay on theme, not a bomb you reach for outside it. Carried by anything else, it is a forgettable +1/+1 stick; carried by a Human, it becomes the kind of small, cumulative edge that tribal aggro is assembled from.
