Unyielding Krumar

The off-color activation cost is the entire design statement. A 3/3 for four mana in black is a body with no upside attached, until you can spend white mana on it: the first-strike pump is gated behind a second color the card's own casting cost never asks for. That asymmetry is deliberate. The creature reads as a flat ground-staller in mono-black, but the ability lives behind a manabase commitment, so the payoff only materializes for a deck already wedging into white. When the second color is online, first strike turns a middling 3/3 into a combat trade-up, letting it eat blockers it could never survive in a straight exchange and attack into bigger bodies without dying. The math only works if you've built toward it. This is a small, honest piece of multicolor-incentive design from an era that leaned hard on punishing greedy two- and three-color manabases while quietly rewarding the players who paid the toll: a common whose ceiling is invisible to anyone reading it as a single-color creature, and modest to anyone who can't reach the white source on the turn it matters.
