Grizzled Leotau

A 1/5 in two colors is a wall that happens to be a Cat, and the math is the whole point. Toughness of five turns aside almost everything the early game throws at it: most aggressive attackers bounce off, most cheap burn falls short, and a 1/5 sits in front of a board until something genuinely large shows up. The single power is the tax that pays for that durability, and it keeps the card honest as a defensive piece rather than a creature that also chips in for free. What makes the body unusual for its era is the color pairing carrying it. Green and white had no shortage of fat blockers, but stapling a five-toughness wall to a body that still counts as a creature for the abundance of tribal and creature-count payoffs in those colors gives it a second life beyond the literal stonewall. It rewards decks that want to survive the opening turns and cash in on bodies later, where a defender that does nothing offensively would not. The leonin framing also lets it ride the Cat tribal current that green and white have flirted with across multiple eras, so the same five toughness that stops a clock can also feed a counters-or-tokens engine that cares about the type line.
