Yoked Ox

One white mana for four toughness and nothing else: a wall in everything but name, built to the barest possible specification. The 0 power is the entire design statement. This is filler at its most honest, a body whose only job is to stand in front of an attacker and refuse to die to small ones, occupying the early turns until something with a plan shows up. Defensive one-drops of this shape are a recurring common-rarity tool: a cheap blocker that buys a turn or two against aggression without committing anything the controller minds losing. The ox does the job with no upside attached, no keyword, no late-game relevance, which is what keeps it a fixture rather than a card with a story. Designs like this earn their slot in formats slow enough that a turn-one body soaking damage actually matters, and in builds that want bodies on the board for reasons unrelated to combat. On its own, it asks nothing and promises nothing beyond the four toughness printed on it.
