Civic Saber

The math is the whole point, and it inverts the usual logic of fixing and greed. A mono-colored creature gets a flat +1/+0, less than the +2/+0 a Bonesplitter hands out for the same one-mana outlay; but a two-color creature gets +2/+0, a three-color body gets +3/+0, and a five-color creature gets +5/+0. The bonus scales with how many colors a creature actually is, which means it pays out exactly to the cards that cost a mana premium to cast in the first place. Splashy gold and wedge bodies that would otherwise be merely playable suddenly read like serious threats with a one-mana artifact attached, and the equip cost stays cheap regardless of the payoff. The floor is honest about itself: on a mono-white token or a colorless artifact creature this does almost nothing, and that flat bottom is what keeps the rate fair. Most cheap equipment just adds a static number; this one asks the deckbuilder to weigh chromatic ambition against the reward rather than treating extra colors as a liability to be smoothed over with fixing. It is asymmetric incentive in a slot that usually adds none, quietly punishing monochromatic efficiency without ever saying so on the card.
