Blistering Barrier

Five power on a body that can't attack is the design joke and the design point at once, but the joke has teeth: a Wall still deals its full power in combat damage to whatever it blocks, so this is a fortification that punishes attackers as hard as it stops them. Most defensive creatures buy survivability with toughness, trading down profitably against the ground assaults they're meant to wall off. This one inverts that budget. The two toughness means it dies to almost any attacker large enough to be worth blocking, but the five power means combat damage runs both ways, and the attacker dies right alongside it unless it has more than five toughness. Early creature design treated power and toughness as roughly fungible, and Mirage-era walls show that thinking in its purest form: a brick that hits back, a one-time roadblock that takes a real creature down with it as it falls. The strategic axis is the trade rather than the stall. A conventional blocker absorbs attacks turn after turn; this one absorbs exactly one, and since combat damage is simultaneous, the exchange only goes the wrong way if the attacker survives five and the Wall does not survive its swing. The card also dangles an obvious payoff for anyone with a way to strip or override Defender, since unlocked offense from this frame is a real rate. Played straight, though, it is a deterrent more than a wall: a body daring an opponent to send something into it.
